Hi, is the balance on your desktop wallet not tying up to the amount reported on MCS? MCS only reports on what it sees in the blockchain. Enter your address in a block explorer to see if it matches.

Here is some text from my FAQ:
Why doesn't my coin balance on MCS tie back to the balance on my desktop wallet?
When you send coins from many desktop wallets such as a QT wallet the "change" is sent to a newly generated address. This is unfortunately not something that MCS can keep track of using the blockchain. You can confirm this in 1 of 2 ways, check your address on the blockchain (not your wallet) and see if the balance corresponds. Or on your wallet, turn on the coin control feature and click on the "input" button on the send tab. Expand the nodes and you should see a balance with a different address. To fix this you must just send yourself all your coins so they all reside in the same address.
We use API's of the block explorers available to read the required data, sometimes these explorers can be behind or suffer problems as well.
