Game doesn't launch – Plants vs. Zombies™ 2 Review

I hope this is just the update but my game refuses to launch. It's always grayed out with Waiting... underneath like it's trying to update, but the update log says it's already downloaded. Please fix this ASAP, since I don't want to lose my money I've invested in this game.
