It is normal for only some users to experience a bug. But no one can assume that when 2.0.5 works on his machine and not on someone else's that it is the other guy's fault. After all, NTTR worked fine less than a month ago.
As cichlidfan said, only ED can fix a bug that they introduced. Users have tried repairs, clean installs, and whatever is recommended, but it won't undo the changes that were introduced with 2.0.5 update 1.
