Stardock....what a mess

Hi,

Didn't play SOSAE for a while. Meanwhile i reinstalled windows 7 etc. This afternoon a friend asked if i wanted to do a coop game. I started up Steam and Sins of a solar empire trinity. And im sooo lucky to get this stardock registration screen (while im already registered at stardock). I logged in with my credentials (all written in a little booklet), but stardock says that the password does not match my email account. Weird...but okay so i hit the link for a password reset and i reset my password which was accepted by stardock. So i tried to start Sins again, but unfortunately, same error. 

I was planning on buying rebellion but after this fiasco i wont. I am soooo tired of proving that im a legit guy with legit steam games...pffff... SO now you will redirect me to the site of stardock. Stardock is explaining some very hardcore stuff with numbers and accounts etc. Im sooo tired of all this crap guys...so tired....

Greetz, Boby
