Conversion fails after recent MS updates

[alanm]

Just recently wmv files and mpg files don't convert to avi. The converted video folder pops up after a few seconds with nothing there. When I restore to a september configuration the program works, after the last microsoft update it stopped. I currently have divx 5.21 loaded with WM player 9 and the runtimes that the program loaded. I just tried it with the 2.7 version and 2.8 version program.

Has anyone else had a problem since the last round of updates by MS?
