Windows Media Player Floating Point Error

I am using AVG 2012 free edition. The Scan found lot of threats. I have removed all items from the virus vault but there is one file that I required. Because of that I am not able to play Media Player Classic and Windows Media Player. It pops up an error message with Code r6002. The error message is ‘Floating point support cannot able to load’.
Please help me to resolve it.
Thanks in advance.
