Pytanie Upgrade Code not work... still in FREE level mode.

I have unlock Advance Upgrade Code from free upgrade , it say successful but doesn't unlock advance mode in menu.

I have the same problem. I had a free account before and purchuased Advanced version from Steam. I edited my profile and added my invite / Steam code, but my product code didn't change to advanced. It is seems to be free.

I hope they can solve this problem ASAP.
