After receiving a payout in April (for sales in February and March), I achieved sales totalling over $100.00 during April, May and June.  I commenced July with a balance of $103.70 and then suddenly, my account balance went back to -$14.48.....a minus figure!!!

I contacted support about this yesterday, and was informed that there was a problem with the server, and I was told that my correct balance would be restored within 4 to 5 days.

Are other contributors experiencing this problem?

My balance decreased by a few dollars for no reason a few days ago.  I couldn't find any refunds, the amount just decreased.  At least it wasn't as much as yours!  I hope it's just a server issue that will be restored soon.  If it's happened to two of us there are probably a lot of others...

Problem now fixed!
