Little help

I can't play my videos on my PC.

I deleted divx, then installed it again, now they are not working, any ideas what to do?

Oh and a box comes up saying can not play, but the sound still works...

Get rid of DivX and get VLC.

I only want the converter because I like WMP.

Does that have a converter? Thats the only bit of Divx I use.
