@Speaker as I have said above, try importing the private keys. Having addresses that you have not seen before is perfectly normal since they are "change" addresses generated when you make transactions.
Dumping the private key and importing them to qt or whichever client you use will solve the problem.
And please *DONT* send your wallet to anyone, be it whosoever, If you can report back with more details after importing key and it still doesn't work, I'll be glad to offer help as much as I can. Thats how we all learn
