Guild Wars Special Edition

i have a question about the game and that is i have the reg. guild wars and i have ordered the special edition one last night and what im wondering is do i have to uninstall my old one and then install the special edition one so that i can get the special things on the new game??
Thanx

No, log into your account and click on Edit Account in the corner of the screen. Choose Manage Access Keys. Enter the Collector's Edition key there.

Alternatively, you could just use the key to make a new account.

by putting in the new access key will it have every thing the special edition is supose to have? im not new to guild wars just never got the special edition one befor so not sure how it is supose to work.
Thanx

Yes, it will give you everything - except for four more character slots, which is why some people opt just to make it separate.

i have 2 acct. now as it is so with the special edition ill have 3 but i wasent sure how adding the special edition would work. thnax

The special edition doesnt have any other features from a normal account, the only things that make it "special" are the extras in the box (CD, art book, unlock card). The unlock card key can only be used once, but can be applied to any account, not neccessarily the one it came with.
If you want an in-game extra, you need teh Collectors Ed. which comes with the Divine Aura (shiney hands of doom).
