@solo said: Post this problem here: http://www.thearender.com/forum/viewforum.php?f=63 A solution will follow. I cannot be certain but uninstalling it should work (removing any Thea files from plugin folders manually also) and deleting some stuff in the 'app data' folder (this is the part I'm not sure of) Thanks for your reply I have posted the problem in the Thea Forum. The problem is posted there from a previous version and I followed the instructions around deleting the path text file but unfortunately SU does not offer me another option to choose the path. Peter
