It's been happening a while now, but whenever I put a disc into my CD drive and wait for the autorun, I get a pop up asking me to log in.
It is a Windows box, no spyware.
Since I dont know the credentials to enter, I press cancel and recieve the message "Cannot access network resource" and then the setup fails to run.
If i right click on the icon and press explore, then run the setup manually, I get the same message.
It's happening with most of my discs. Some work, some don't. Mostly the newer games don't work.
