Keep getting error code -3

I'm trying to convert an album I bought into mp3 format and I keep getting this error. I've installed/reinstalled Quicktime like other posts have suggested but it hasn't worked. Strangely, only this album is having the problem, the others are fine and convert without problems. How do I fix this issue?

This is on a Windows 8 laptop. I've tried restarting the computer, reinstalling iTunes, and reinstalling Quicktime.

The album is 'VA - EDM Euro Trance Classix 1' for anyone wondering.

Edit: I tried redownloading the album through my 'purchased' albums, but apparently I didn't purchase it. >_>
