I have a problem. I'm trying to load project file to the unit but I get error message that "In order to upgrade the MD4-5 to version 4.00 and later the module must first be upgraded to at least version 3.17". How do I do that? I've tried with three different versions of the project file but I guess they all are version 4.00 or later. I've tried this with IQAN run 4.03, 4.07 and 5.xx and I get the same error message every time.
