After I've installed the Virtual Cop2, the software asked me to install the DirectX5.0 and upgrade my sound blaster version. After all the installation have been completed, I have to restart the computer, then the computer shows that there is an "msrgrv" error. I can't start the Windows 95 normally and can't log onto the internet again. I try to erase the directx5.0 and the game, but the error still exsists there. When the computer was erasing the game, it shows that if the game has been erased, there would be some changes to the system. Should I erase the Window95 and reinstall it again? Or is there any simple method?
