vmware
months ago i used to have vmware workstation installed in my pc.i had no problem with crossfire and i could open 4 of them
now i decided to use vmware player .i did everything right but everytime i start crossfire a message pops out saying"client file corruption detected...|
wtf?
update the client (redownload it! and install)
They don't allow more the use of VMWare, they can detect it and becoming impossible to use it in normal cases.
