"Exists in your account" when it doesn't

Re-sync your account. Still have this problem? Have you played this during the free weekend? You have to wait 2 weeks until you can enter giveaways for it.

There are around ten threads about this, and they can be seen by simply typing 'Magicka' into the search while on the forums. I'm betting a few of them would have an answer that would be easier than making a new thread.

I think it stays in your account for 2 weeks after the free weekend.
