Make sure you install the latest version of Flash ... they now have one for both the x86 and x64 version of Internet Explorer. Having said that, make sure you're using the x86 (32bit) version of explorer. No matter what though, you should upgrade Flash.

If you are using Steam, you may need to rebuild the game before starting..

Kinda also help if you tell us which game you are playing.

Yah, stated previously by Saltgrass, if it's through Steam rebuild the game. Also, depending on the game you are playing, there might be a separate launcher for the game settings... so you may have to muddle through that as well.
