itunes problem

so im getting the error 4450 for itunes whenever i try and burn a cd. ive tried reinstalling and checking firmware and all of the like but cant figure out what to do. any help?

 

It appears to be a copyright protection error message within Itunes.
Are the files you are trying to burn purchased from Itunes?

 

no its not. its music i made myself using reason. i converted the files to mp3 format already so that shouldnt be it. i also tried burning it in wmp and that didnt work, and ive tried to burn other things and none of that is working now either. i have no idea what to do

 

What type of disc are you burning them as? Ausio disc or MP3 disc?
If MP3 windows can burn the files,
Or Nero is good

 

i tried all of that. none of its working. my only guess is something with the drivers or registry got messed up. but i dont know how to fix that
