I use an Instron 8801 with NI GPIB card and a main component of the software called WaveMatrix in which you make and run tests throws an error code "File Error #10020 Value cannot be null Parameter name: value" whenever I try to save a test method. The software has no issues saving data from running pre-installed test files. The issue is when I try to modify the test parameters and save the method file. Has anyone seen this before? I am wondering if it may be GPIB related. Instron claims they do not know what this code is and it may be due to some permissions settings on my computer and not their sofware. This is the admin account and should be able to save any files so its not a permissions issue. DAX also works with no errors. Oddly enough the software will save methods on another PC I have running an Instron 1331 with an older GPIB card with no errors.
