sry my wrong, I should have explained that I have payments coming to this wallet for a few years time every week. I think :/ otherwise I would have just done as said earlier:)
Use pywallet and extract the private keys. You can then import them into another wallet. You don't need to import all the keys just the ones you get regular payments on. I would save a copy of the encrypted wallet.dat and an encrypted copy of the pywallet dump offline just to be safe.
