From my perspective it was worth the low price to get the crossgrade (I can’t remember how much, but under $100). I did think the disc exchange was a bit odd. I had no plans to purchase an Intel Machine but didn’t want to fall behind. When the crossgrade arrived it sat in the box until I had a break between projects. I know this doesn’t help you now, but the next time consider copying your discs (to media or as images on a hard drive) and get the upgrade. I hope your situation will be resolved to your satisfaction.
