You paid the same price any other person would pay. You just paid for it earlier. Are you seriously freaking out because there is a three hour emergency maintenance to fix issues on launch day?
Wait, I have another question. Have you ever played any other MMO at launch? Emergency maintenances, hotfix patches, etc, are all part of the world of newly-launched MMOs. It comes with the territory. At least we had the option to download/update the client without having to go pick it up at the store first. That's probably the most agonizing part of MMO launches of the past.
