Early access code is "invalid"

[fireslash]

the code by itself is not invalid but your account registred as a steam is on the way .i happen to have the same issue having to buy a steam version after i bought a windows version where it stated an invlid code for me .i dont play through a steam i never did yet it states that i am registered as a steam , probably it happend because maybe when u started playing the game , u registered you account with the free give away registration code , and that might be a steam one though the game runs through a direct downloaded launcher from the internet .there is no way around changing the type of the account but the only solution so far is to buy a steam version then install the code to your account , you dont have to play in a separate launcher .buy and get the code from steam , you dont have to download the whole thing again ... thats what i did

they also refunded me for buying the wrong version
