I've run into all the same problems listed on this forum - activation, issues with other programs, etc.  Just too buggy a Beta for me....but now I am unable to completely uninstall... I can delete some files, but none of the dlls.  When I tried to run uninstall I get the message that it can't uninstall because lua5.1.dll cannot be found.   Some dlls seem to be in use and that's why they won't uninstall, but none show up in task manager or startup.   I just want to get rid of this program until it's out of Beta. Any ideas??
