So I use Divx Player and it's been stop working and then working again when I reinstalled Windows 7. For the past few weeks I've just been running on Windows 7 trial without activating it and I activated it last night. Tonight I tried to play a video on Divx Player and it didn't work. At first I thought it was the video so I tried a bunch of other videos and none of them worked. Then I just realized that activating windows caused the problem, because it was always fine when I did a fresh install and it stopped working after I activated it last night. So, can anyone help me fix my problem without me having to do a fresh windows install again?
