PE 6 stopped working

PE 6 worked fine for a month on Windows 10 but now gives this message and needs task manager to quit. Reinstalling didn't fix the problem.

Not sure but have logged details and asked the PE6 team to investigate.

Have you recently upgraded PE6 or any other software, installed new anti-virus software or undertaken a scan recently, or done anything which might be significant between it working and now failing ? How long ago did it last work ?

The file mentioned in the report is not a PE6 file and not something that would be used within a normal PE6 start up. We would search for that file name in the registry and see if it appears as a corrupt registry entry, if so delete the entry.

I don't understand the registry. This appears when you close the message window but it doesn't work. Very strange.It's worked since I installed it 2 months ago.
