I recently purchased a cd-burner and the software that came with it is Nero 5.3 and I am having all sorts of problems with it. The initial installation had all sorts of errors in it and I went to the Nero website and did an update and was finally able to finish the installation. Now my most current problem is I do not have the serial number to the software so that I can actually use my cd-burner software. The jacket the software came in did not have the serial number on it and I do not know how to go about finding the serial number. I tried doing a run with regedit to find the serial number on my computer, but it shows nothing. Is there another way to find the serial number short of buying the software? I'm getting very discouraged with this whole process and I'm ready to just quit. I'm hoping someone can help me so that I can finally use my cd-burner.
