Do you have your seed with you? This is 12 letters long and you should have either memorized it or written it down somewhere. Even if you don't have it, it should still be possible to recover your wallet as long as the files weren't overwritten but it might not be easy.

EDIT: Perhaps you can try downloading Electrum Portable, running it, and then replacing the wallet.dat it creates with your copy of wallet.dat?

EDIT 2: Not sure if Electrum Portable has an "import" feature but if it does then that could work also.
