Dear Sir,
The FMC30RF is not supported on ML605 when connected to PCIe, this is the reason why this is grayed out. You could try to select a FMC150 and there you will see the PCI droplist enabled.
As far as the issue is concerned, I have seen this problem on my machine when running the 4FM Analyzer from 4FM Control GUI tab. Can you try to run the analyzer (4FM_FMC_Analyzer.exe) directly from the executable under "C:\Program Files (x86)\4dsp\FMC Analyzer".
This issue disappeared after re installing my machine which was scheduled earlier. We have tested on 10 difference machines (11 including mine) and we have not seen the issue. Note that this tool is not very mature and you are providing me with the first report about this new tool.
Let me know if that helps,
Arnaud
