Have my wallet address but cant find my wallet.

[winlosewin]

Hi.
I have my wallet address, but cant find my wallet. The wallet is unencrypted. Am using MultiBit, and when I attempt to open wallet it will not find it. It was in MultiBit under the transaction view, but I downloaded the new version, and now I dont see any transactions at all, under either version.
Have done advanced searches on my computer for the wallet address and can only find a Multibit text document containing the wallet address. Looks like a log.
Please help.

The wallet.dat file should be under your user profile.  May not find if you have the checkbox marked to Hide Protected System files in Folder Options.

In windows 7
c:\users\%username%\AppData\Roaming\MultiBit
