Unknow error

Impossible to get read access to the process GameServerCS.exe (ID:11)
Same for GS.
Using Server start up [BoR]
MuEngine S6E3
Whats wrong ?

1st of all What OS you have?
Second you use the free muengine files version right?
why you changed to startup bor btw?

Win 7 x64 , MuEngine free , Startup was with files...

Tried running as administrator?
