question for you,

Did you uninstall the prior version befor installing 1.20?

if not thats where part of the problem lies. there came a point where It happend to me also. what I had to do was reinstall a prior version and then uninstall it. then after that and deleating all files from my xolox folder (or transfering them to a other folder for keeping) I installed 1.20 and am not haveing any problems now.

so for others out there. does anyone have copies of the older versions of xolox(1.18, 1.19 ) on some site? or know of a site that does?
