Help me to solve the Flash player problem.....

I have updated my flash player to version 12 and there is a red flash player icon in the add or remove programs in the control panel(screen shot attached). Flash worked well in Firefox(trying with Facebook). I rebooted my pc and then the flash icon in add or remove programs in the control panel turned to a white blank symbol(screen shot attached). Opened Firefox and loaded Facebook...but Firefox freezes and as it is not responding I have to forcefully end Firefox process. This happens with every versions of flash player and therefore I'm unable to use Firefox to view a lot of web pages. Please help me.... :-[
