It all started with a simple install Daemon tools. After using it for a while, I no longer needed it, so I uninstalled the program. Less then a day later, I wanted to burn a CD using iTunes. Unfortunately, I got the error (4450). This is not the first time I got this error. Last time, to remedy this problem, I installed SPTD v1.50 and it fixed it perfectly. Now, it didn't work. I can't burn anything with any program and am having serious CD drive trouble. For some reason, it says the burner is in use by another program, though it is not by any other program (as far as I can tell) or by any other user. So iTunes and Roxio won't burn, I can't just drag and drop with Explorer. I have tried updating my drivers and uninstalling/reinstalling my CD drive to no avail. Any help?
