Hi all
in another post I wtote about V21 crashing right on startup while processing the plugin factory. On recommendation of @Steve_Rhoden and @Reyfox I uninstalled the Ignite pro package and V21 opened without issues.
I then vaguely remembered something - I had this issue before and by a weird intuition, I tried changing various Windows settings.
And you know what - my language settings were set to English-Belgium instead of English-US!
I changed it to US and now Ignite works in V21.
Now that is a weird one indeed...but maybe it can help someone here with the same issue..
