Sorry if on the wrong board.

I have a iBook G4 and the other day I deleted the Quicktime on my computer to install a different version. Now I can't dl any version because it say a new one is already there. However nothing will play. I've searched many forums looking for answers but nothing suggested helps - running a search and deleting everything (including library receipts), dling other player (VLC and Divx won't dl), and I do not have the original discs so I can't reinstall that way. I did find one player that runs .avi, but I need .wmv

Help?
