bestbuy, do I have this right: you installed MultiBit, then sent Bitcoins from your Mt. Gox account to an address in your MultiBit wallet. That wallet then got removed. Is that correct?
If that's what happened, your options are limited:
- If the wallet file still exists, you may be able to reopen it in MultiBit. The file would have been in %APPDATA%\Roaming\MultiBit on Windows, with a .wallet extension.
- If you ever made a backup of your private keys from MultiBit, you can import those private keys to MultiBit, or to another wallet.
If you don't have the wallet file, or a backup of it, and you don't have your private keys, you're probably out of luck. Sorry.
