I was having some computer problems and a friend offered to clean up my computer to make it run faster. Now I can't get Media player to run, my printer will no longer print and the windows file search program won't run. I tried downloading another copy of Media palyer 11 and that doesn't run. If I click on a wave file media player won't run. If I just try to start media player directly it still won't run Any suggestions on what to do would be greatly appreciated.
