"a error occured while retreiving your auction"

[JSL]

yes u got ur money. it happens to me all the time. its when u collect all ur money to fast from the sold items, so the first time sometime doesnt work.

This, and what Battlelock said below it, are exactly right.

You'll receive this message when you click too fast on retrieving items or money.

Don't worry, though. It's there!
