I added the CDKey that came with my copy of GW:NF and it began to give me a 10 hour countdown stating that the CDKey I entered is just a trial key. Naturally, I checked the game box again to make sure I hadn't entered one of those trial keys they provide you with for numerous games.. it was indeed the proper CDKey

I fired off an e-mail to NCSoft support and within a day or so they replied saying my ticket's been escalated. I have not yet heard back. Here's a copy of the e-mail I sent them via their website:
"Hi there,
This afternoon I went to my local Future Shop and purchased a copy of Guild Wars: Nightfall. My acccount already has access to Prophecies + EotN and I've been playing the game nearly since release a few years back. When I went to add the NF CDkey, it said that it is a trial key and began to give me a 10 hour countdown. Did I just get a wrong CDKey? Should I return to Future Shop and exchange my copy for another? The CDKey that came with my copy is XXXXX-XXXXX-XXXXX-XXXXX-XXXXX. Any help would be greatly appreciated.
Regards"
Recently realizing that Future Shop doesn't even accept returns or exchanges on software that's been opened, I'm thinking I'm kind of screwed. Has anyone ever had this happen before? Should I buy a new copy or wait it out for their 'escalated' response?
