I found out a few days ago that my windows media player on my laptop got corrupted. it reads every wideo in inverted colors and i cant fix it. i scanned for viruses and got nothing, so i was going to delete it and redownload a new one. Problem is that it wont let me delete it because i dont have permission to make changes to it because i dont have permission from some company, (didnt say microsoft) and i also couldnt redownload a new on ebecause on the windows website it doenst give you a download button it just says that it is included in windows 7. what do i do?
