Query: Worked perfect at first, then I get every error msg it has.

I got this from Best Buy a couple of months ago, installed it, and burned cds with perfect speed and perfect quality. All was fine through the first 30 or so cds, but after that I started getting weird error messages in Nero (the one I always used with it). So, I contacted Nero tech support and asked them what the problem could be, took a week and a half to get a response, and finally they ask me if my system meets all the requirements. Here's the kicker: I gave them the system requirements for the CD Burner, my system specs, and how I had the burner set up. So after that I contacted I/O magic's tech support, and I still haven't gotten a response after a week. So this thing is coming out of my computer and going back to the store. If you're thinking of buying this, I recommend making paper airplanes with your money instead. They're alot cheaper than the cds I had to buy, only for them to be turned into coasters.
