What happens when you restore the wallet? When you say "you don't see anything", do you mean the app can't find the wallet file to restore it, it finds it but won't restore at all, or it does restore but shows you an empty wallet? If it doesn't restore at all, does it give you an error message? If it does restore, do the addresses in the wallet match the addresses you have above? Do they begin with "1" or do they begin with something else?
If you are going to go down the route of dumping your raw private keys, then you should preferably be doing this on an offline computer for security reasons.
Now I've renewed my wallet. I waited a long time for 60 months to load.
Now I see mBTC 0.00 - so the wallet is empty.
No error message.
The wallet address is different and there is a comment that this address will change after each transaction for security reasons.
In the first post I wrote incorrectly what my backup file "bitcoin-wallet-backup-2014-08-18" contains
It correctly contains the following:
U2FsdGVkX1809I / daCCv4Qor7gyUZNvp00Z3Z5TMpJKSRpvDVs1wxikwES5UiKeU0Z4R ....
and many other characters
