I installed a GeForce 8400gs on an Acer Aspire xc600 and after I did some driver updating I get this logging into my game. Any way to fix this? Thanks.

c:\windowns\system32\nvd3dum.dll is either not designed to run on windows or it contains an error. try installing the program again using the original instillation media or contact your system administrator or the software vendor for support. Error status 0xc000012f.
