Frustrated with Windows

I put off downloading the Windows XP Service Pack 2 for a while because I just didn't want to deal with it, but last week I had a little time and decided with certain security threats showing up maybe I should go ahead and update. Well, I have a Sony CD-RW drive that now no longer burns. Windows and Windows Media Player do not recognize it as an RW. I went to the Windows website for and update and to look for the most current driver, but I am current according to Windows. Sony said to seek support from Microsoft (like anyone every gets personalized support for Microsoft without paying out the ass...) so, please, any suggestions are welcome!
