I got the 10 day trial, and getting full version

[nylui]

I tried the 10 day trial, its a really good game. Im buying it this afternoon. The game took a long time to download, do i have to download it all over again? So what, i got the trial, i buy the full version in store, then what?

The box contains disks containing the same client you've just downloaded, so you don't have to use them. However, as well as the CDs there is also an account key inside the case, perhaps underneath a disk or on the back of a booklet. Use that to create an account on Blizzard's website for your region. Have a credit card ready.

Not sure if you have to download the whole thing again... Essentially once you D/L the cd's WoW and TBC (if you intend to buy it) Blizzard will essentially update all the patches for you.

You don't have to download it again, just use the key to get your account.

MAKE SURE you go to your account page and log in - then click on UPGRADE account. If you don't use this method you will lose your existing characters and be starting over from scratch.

I never went and bought the game from the store - after downloading the free trial I just opened up the "my account" page and clicked upgrade account and accepted the one time charge (think it was $20) to my credit card, selected how often I wanted to pay (1 mo, 3 mo, 6 mo) and got the message that all content was now unlocked for my account. Have been playing ever since (3 months now).
