This probably goes without saying, but it could be an easy thing for someone to miss and get concerned about.  The unreliability of Mt. Gox at the present time appears to have caused the trade and depth data to get way out of sync on bitcoincharts.com.  (bitcoinmonitor.com seems comparatively reliable for trade data.)  Also, when Mt. Gox does load, it ought to show your correct balance, but it may fail to display your open orders (an AJAX issue).  So just a PSA not to panic if you don't see what you expect.
