It looks like they finally got the trade-in page working. At least mostly. After never getting anything better than invalid COA/PID and incorrect city/state etc. since they first set it up, I finally got to the final confirmation page. Of course, I had to change payment methods from Discover to AMEX as for some reason they offer Discover but then flag it as invalid when you use it, but hey, they fixed everything else, at least for me. Since I will be receiving my version from Directron tomorrow (if it is not rescheduled by UPS again) I didn't submit, and I had decided to keep my 32-bit system anyway since I have hardware and software that won't be supported, so dual boot is for me until all that is resolved, but hope all who have had problems with the exchange pages will try again and report back any new problems.
