MeGUI 6.6.6.6 - Can't launch it

[pooksahib]

Hi. I downloaded MeGUI 6.6.6.6, adjusted the settings to my liking and indexed a video. All worked well. I then UNticked the box saying 'always use the included avisynth' and MeGUI just shut down and won't reopen - the logo appears for a second (as it normally would) but then disappears. So I have MeGUI 6.6.6.6 on my PC but can't open it.
Does anyone know cause and cure for this weirdness? Many thanks.

See if you have a settings.xml in the program folder. If so delete it and retry

Thanks dave. Only half way there though: every time I untick that box the story repeats. Damn strange, got any ideas?

No. Sounds like a bug in the new release. Report it to the developer

There's a 'cure'... uninstall my Repository avisynth. Obviously not ideal. As you say, sounds like a bug.
