A2A Piper Cub AccuSim Problem

While I await a resonse from A2a Thought a query here might bring an answer.Had to reinstall Windows when it could not install the latest Mcrosoft update. After exchanges with Microsoft decided to reinstall Windows7. That was painless (amazing). However, the AccuSim part of the A2a Piper does not bring up the menus for maintainance and other function. It does bring up the map ok. Reinstalled the aircraft and AccuSim but did not fix it. Prior to the Windows7 re-install it worked as it should.2.5ghz dualcore, 2gb memory, 8600 256mb videoand 20 inches of snow!
