No harm done, you were supposed to remove the CD before rebooting (it says so even) but it's fine even like this.
Thanks a lot for the suggestion. I know that this is an old thread, but I had to register to express my thanks. I have tried to reinstall the drivers and afterwards I got the black screen with the previous posted message.
After seeing your reply, I removed the disk and restarted and it worked.
Thanks a lot.
