The charts have been really buggy, but they don't affect actual earnings I don't think.  It appears you're getting .068 BTC here soon.  I searched your address on the middlecoin homepage in google chrome.  You should do that to check your balances if you aren't, as it seems to be much more up to date.  Do Ctrl+F and plug in about 5 characters of your address if you've never done this before.  Not sure how good that is for your hashrate, but that seems pretty darn good to me.  Around $60 or so.  

I REALLY wish I had my 6770 here today that's on its way.  Could've cashed in even more.  Oh well, I shouldn't get too greedy.
