Hmm, tricky... log in to Battle.net and navigate to your WoW account. There were a few issues when I set up my account and I've ended up with two under the same email & login - WoW1 and WoW2. the former was my trial account - can't join guilds, can't use the auction house, can't whisper or yell, nerf-mode basically. the second one has all my expansions and a 6-month recurring sub on it. Just check to see that you've only got one account listed there, make sure it says it's the full version and not a trial and if you've got two be sure to log in to the right one when you load your WoW client.
Edit: I won't be around until after Monday really, the gf goes back home for a while then
