It’s shame that there is nothing to do with your left free trial days.
firstly,make sure you do have your caps unlocked.
secondly ,checkout your keyboard and how many numbers you’ve typed. maybe there’s something wrong with your keyboard’keystokes
If all these doesn’t work,then go to the game store and ask them, BUT i don’t thik the code patched with disk need activate.

btw,what kind of cord you bought? TBC or a new account code?

If you install World of Warcraft and create a new account with the key that came with your discs, then you will be using a new account, and will not have access to anything gained during your 10-day free trial.

Troubleshooting:

–Did you use a Burning Crusade trial and are trying to install Classic WoW? Did you buy Burning Crusade without having WoW installed first?

–Were you using your existing account name with the new key? This will definitely cause errors, since the name and key are tied to the trial version. You will need to upgrade your trial account if you want to keep any of that progress.

–Your game store does not need to scan anything to activate it. The game discs and key, as well as game time cards are good to go out of the box. There is no activation process done at the store.

–Try “Upgrade Existing Account” when you go into Account Management on the World of Warcraft site. Since you’ve got your info on a free trial, you should upgrade that account instead of starting over. It will save you a lot of headache.

–If you cannot solve this issue in Account Management or with the FAQ on WoW’s website, try calling their Customer Service line. They should be able to help you out.
