Was it running fine before?

yes it was fine before. the problem started suddenly from yesterday after I had a power shortage.

Okay first go to the following directory "yourusername" is the username in your windows/system

C:\Users\YourUserName\Appdata\Roaming\mmocoin

First, copy the wallet.dat and make the backup of it somewhere (copy and paste it somewhere or send it to your secondary email) It is your main file where you keep all the mmocoin balance

Now delete all the files and folders except wallet.dat (do not delete wallet.dat) and then restart the MMOCoin-Qt.exe file & It will re-sync the wallet and you will be able to access the wallet again.
