PlugChecker.exe not working

[Nullgrad]

I am getting this message PlugChecker.exe not working when trying to use certain vst plug ins, Native Instruments FM8, UVIWorkstation and Arturia V Collection seem to be the ones that work one minute and then don't the next, usually after I have installed new software that use ilok or elicence.

Can anyone suggest what is going on and is anyone else having this problem, because it is "doing my head in" .

I should have added that these plug ins work in other vst hosts such as tunfish and cubase 5

update the C:\Program Files (x86)\Orion\vstcfg.txt file
i have added FM8=1 inside the file

I have tried that it doesn't make any difference - it was working previously without being added to that text file.
