How to add Serum to account when bought from Splice?

Sorry if this asked before, but i didn't find answer.

I had serum rent in Splice and now i bought it and i have serial. How do i add it to my account so i can DL updates? I only see LFOTool and Cthulu that i bought via Xfer.

EDIT: I can't use the "forgot password" as i have different email in Splice and in Xfer.

Cheers!
