Codec Pack Brought Kazaa Problem

[fiasco]

after instaling the latest codec pack i cant seem toview preview of movies i am downloading. i keep getting prog has performed an illegal action you have to shut down what could the problem be??any solutions

some users have had this problem with codec pack 220, download and use 210 and it should work. You could also try and find just avi preview and install it, that may fix it but I would stick with 210 instead
