I have a Windows 7 guest that was happily running in Player 15.5 under Windows 8.1 build 9600, but ever since I fixed my dual-monitor configuration in Windows 8 so that the 2nd monitor works and the resolution behaves correctly on the 1st monitor, the Windows 7 guest has crashed with a Blue Screen of Death (the crash screen says Windows 7 was loading the ndis.sys driver at the time of the crash).

Does anyone have any suggestions?  Maybe I simply need to reinstall Player to take into account the new monitor drivers?
