I see. I ended up sending him the PM, and got a reply from Ausaudriel that pretty much said using a different email for my paypal than what is used for my account here (and most other places) threw the system off.
I ended up sending a mail to Rukario stating as much, and I think he/she (I'm thinking she) did the same.
That's fine! :3 Just private message "Rukario" and tell him how much you donated, when you did, and from what email/paypal. Then you'll be good to go and just have to wait!
