ToME: the Tales of Maj'Eyal

Huge fan here. Heard of release of Ashes of Urh'Rok and rushed to buy. Bought Tales a long time ago. Tried to buy Ashes of Urh'Rok thru steam and was informed I needed to buy tales first. Tried to buy Ashes of Urh'Rok thru TE4 website and was informed I didn't have enough coins. So, donated 5 euro and got 50 coins. Now I go to the Ashes of Urh'Rok page and click the 'Get it now' button at the bottom, only to be told I still don't have enough coins.

Why isn't this incredibly easy? What am I doing wrong?

Maybe the transaction hasn't cleared yet?

No, the transaction has cleared. My 'balance' is listed as 50. The cost of the Urh'Rok thing is 40.

Its incredibly easy to buy. How did you break it?
