You are right. I have created a small test file. Since I don't know if an attachment makes it to the list, I put it Base64 encoded here (it's just 3k). All one has to do is. 1. Start the Programme, a SIMetrix Command Shell will open 2. File -> Open Schematic, chose test.sxsch. Now a new window should open. It will contain an incredibly complicated schematic ;-). 3. Press F9 to start the simulation. In the Command Shell one will find the above error message. Thanks, -Andre begin-base64 660 test.sxsch EgBTSU1ldHJpeCBDb21wb25lbnQDADQuMR0AAAAEADQuMjYEADQuMjEbAAAAAwADAGduZAMAcmVz CQBkY19zb3VyY2UDAAkBqwEAAAkAZGNfc291cmNlEQBEQyBWb2x0YWdlIFNvdXJjZQcAU291cmNl cwYABwEUAAAAiP///6gAAAB4AAAAqAAAAAcBFAAAAIj///8IAQAAeAAAAAgBAAAHARQAAADQ//// 2AAAADAAAADYAAAABwEUAAAA0P///zgBAAAwAAAAOAEAAAcBFAAAAAAAAAAAAAAAAAAAAKgAAAAH ARQAAAAAAAAAOAEAAAAAAADgAQAAAAACAAYBFQAAAAAAAADgAQAAAgAAAAAAAQBOBgEVAAAAAAAA AAAAAAABAAAAAAABAFAFAAIBHQAAAAAAAAAAAAAAAAAAABoAAAADAFJFRgIAVj8CAR4AAAAAAAAA AAAAAAAAAAAKAAAABQBWQUxVRQEANQIBHgAAAAAAAAAAAAAAAAAAAEAAAAAFAE1PREVMAQBWAgEl AAAAEP///wwDAAAAAAAAyAEAAAkAU0lNVUxBVE9SBABEVUFMAgEwAAAAEP///5QCAAAAAAAAyAEA AAsAVkFMVUVTQ1JJUFQNAGVkaXRfZGNzb3VyY2UAAIj/AAB4AOABAQAAAAkB4AEAAAMAcmVzFABS ZXNpc3RvciAoQm94IHNoYXBlKQgAUGFzc2l2ZXMGAAcBFAAAANz///8OAQAA3P///1oAAAAHARQA AADc////WgAAACQAAABaAAAABwEUAAAAAAAAAA4BAAAAAAAAaAEAAAcBFAAAAAAAAABaAAAAAAAA AAAAAAAHARQAAAAkAAAADgEAANz///8OAQAABwEUAAAAJAAAAFoAAAAkAAAADgEAAAAAAgAGARUA AAAAAAAAaAEAAAIAAAAAAAEATgYBFQAAAAAAAAAAAAAAAQAAAAAAAQBQBgACASUAAAAAAAAAAAAA AAAAAADAAAAACQBTSU1VTEFUT1IEAERVQUwCAR0AAAAAAAAAAAAAAAAAAAAaAAAAAwBSRUYCAFI/ AgEfAAAAAAAAAAAAAAAAAAAACgAAAAUAVkFMVUUCADFLAgEyAAAAAAAAAAAAAAAAAAAAwAAAAAkA REVDU0NSSVBUEQBpbmNfZGVjX3Bhc3NpdmUgMQIBMgAAAAAAAAAAAAAAAAAAAMAAAAAJAElOQ1ND UklQVBEAaW5jX2RlY19wYXNzaXZlIDACAR4AAAAAAAAAAAAAAAAAAABAAAAABQBNT0RFTAEAUgAA 3P8AACQAaAEBAAAACQHwAAAAAwBnbmQGAEdyb3VuZBUAQ29ubmVjdGlvbnM7VGVybWluYWxzBAAH ARQAAACI////eAAAAHgAAAB4AAAABwEUAAAA6P///8AAAAAYAAAAwAAAAAcBFAAAALj///+cAAAA SAAAAJwAAAAHARQAAAAAAAAAAAAAAAAAAAB4AAAAAAABAAYBFwAAAAAAAAAAAAAAAQAAAAAAAwBH TkQCAAIBHgAAAAAAAAAAAAAAAAAAAMAAAAAFAFZBTFVFAQAwAgEfAAAAAAAAAAAAAAAAAAAAQAAA AAcAbmV0bmFtZQAAAACI/wAAeADAAAEAAAAAAAAAAAAAAAcAAwABAW0BAAABAAAAAAAAANgJAACQ BgAAAAAAAAAAAQBDAAAAAAAAAM0AAADvAAAAAwByZXMHAAIBJAAAAAAAAAAAAAAAAAAAAMAAAAAG AEhhbmRsZQIASTEAAAAAAgEiAAAAAAAAAAAAAAAAAAAAQAAAAAUATU9ERUwBAFIAAAAAAgE2AAAA AAAAAAAAAAAAAAAAwAAAAAkASU5DU0NSSVBUEQBpbmNfZGVjX3Bhc3NpdmUgMAAAAAACATYAAAAA AAAAAAAAAAAAAADAAAAACQBERUNTQ1JJUFQRAGluY19kZWNfcGFzc2l2ZSAxAAAAAAIBIwAAAEMA AAAAAAAAAAAAAAoAAAAFAFZBTFVFAgAxSwAAAAACASEAAABDAAAAeAAAAAAAAAAaAAAAAwBSRUYC AFIxAAAAAAIBKQAAAAAAAAAAAAAAAAAAAMAAAAAJAFNJTVVMQVRPUgQARFVBTAAAAAACAAAABABW MV9QAQAwAQE4AQAAAwAAAAAAAAAIBwAAkAYAAAAAAAAAAAEAlwAAAAAAAAAEAQAA7wAAAAkAZGNf c291cmNlBgACASQAAAAAAAAAAAAAAAAAAADAAAAABgBIYW5kbGUCAEkzAAAAAAIBNAAAABD///+U AgAAAAAAAMgBAAALAFZBTFVFU0NSSVBUDQBlZGl0X2Rjc291cmNlAAAAAAIBKQAAABD///8MAwAA AAAAAMgBAAAJAFNJTVVMQVRPUgQARFVBTAAAAAACASIAAAAAAAAAAAAAAAAAAABAAAAABQBNT0RF TAEAVgAAAAACASIAAACXAAAAAAAAAAAAAAAKAAAABQBWQUxVRQEANQAAAAACASEAAACXAAAAeAAA AAAAAAAaAAAAAwBSRUYCAFYxAAAAAAIAAAAEAFYxX1ABADABAakAAAAEAAAAAAAAAHAIAADoCAAA AAAAAAAAAQAAAAAAAAAAAAAAAAAAAAAAAwBnbmQDAAIBJAAAAAAAAAAAAAAAAAAAAMAAAAAGAEhh bmRsZQIASTQAAAAAAgEjAAAAAAAAAAAAAAAAAAAAQAAAAAcAbmV0bmFtZQAAAAAAAAIBIgAAAAAA AAAAAAAAAAAAAMAAAAAFAFZBTFVFAQAwAAAAAAEAAAABADAHAAABKwAAAAAAAABwCAAA6AgAAAAA AQDYCQAA6AgAAAAAAAABADAGACs6UjEjTgABLgAAAAAAAADYCQAAGAYAAAAAAADYCQAAkAYAAAAA AAAEAFYxX1AGACs6UjEjUAABLgAAAAAAAAAIBwAAkAYAAAAAAAAIBwAAGAYAAAAAAAAEAFYxX1AG ACs6VjEjUAABLgAAAAAAAADYCQAAGAYAAAAAAAAIBwAAGAYAAAAAAAAEAFYxX1AGACs6UjEjUAAB KwAAAAAAAAAIBwAAcAgAAAAAAAAIBwAA6AgAAAAAAAABADAGAC06VjEjTgABKwAAAAAAAADYCQAA +AcAAAAAAADYCQAA6AgAAAAAAAABADAGAC06UjEjTgABKwAAAAAAAAAIBwAA6AgAAAAAAABwCAAA 6AgAAAAAAQABADAGAC06VjEjTjMAAAAuU0lNVUxBVE9SIFNJTUVUUklYDQouVFJBTiAxbQ0KLlNJ TVVMQVRPUiBERUZBVUxUDQoBAAAAAQAAAAAAAAAAAAkAAAB4AAAAAAAAAAAAAAAAAAAAAAAAAAAA Ac4AAAAFADYuMDBjMABCYXNpY3xBRHxNaWNyb258U2NoZW1hdGljfEFkdmFuY2VkfERlbW98UnRu fGJldGEIAAAABAAAAFBhdGgAAAAACAAAAFJvb3RQYXRoAAAAAAkAAABSZWZlcmVuY2UAAAAACwAA AFVzZXJWZXJzaW9uAQAAADEIAAAAUmVhZG9ubHkFAAAARkFMU0UKAAAAVXNlclN0YXR1cwAAAAAN AAAATWFnbmlmaWNhdGlvbgEAAAAxBwAAAE5ldE5hbWUAAAAAEAAAAAAAAAAAAAAAAAAAAA== ====
