So just a question, with the transfer now in the hands of Pearl Abyss how can we steam players buy Acoins (Essentially your version of Kakoa Cash I Presume) and exchange them for pearls? I am no longer allowed to use my steam wallet? Also when i try and do it Via Launcher it tells me i have to log into a PA account? Can you please explain this new process to me? 

- Steam users cannot purchase Acoin on the official website. Instead, Steam users can purchase Acoin from the in-game [Pearl Shop > Acoin Recharge] menu.

Will try it now.

Did not found any other hint.

Friend got the same Problem , any solutions now ?

Going over ingame shop has the same result, ask to log in , when it comes to payment method.

but hes already logged in ....

2 Of my Friends also have this Issue, both Steam users who can not buy ACOIN's.

Any CM/GM on the case yet? Or is it better to write a ticket?

Same here, i cant buy Acoins on steam
