Question about Early access-

I bought from this forum and official page the Early acc. for PoE 2 and i've got the key.
Now i don't understand form where to download the client?
On steam it ask me to Buy it again? And my account here is on steam too.
What i do? Never did any early acc. before this one.

Omg im so stupid. I used the key on steam and i got PoE 2. Thanks a lot and so sorry
