I recently bought Windows XP. I formatted my harddrive to install the software. I have two cd machines in my system. One of them is a Yahmaha burner, the other is the Sony CDU5211 cd rom. I have installed from the sony my anti virus, macromedia software, microsofts trips & streets. Then I was going to install microsft office, but then decided to install easy cd creator platinum. It installed properly from the sony, however my cd rom does not work anymore. This happened once before and I thought my cd rom just died so I bought this one, the sony. Is easy creator messing it up? Is there anyone else that had this same problem?
