I downloaded Bitcoin-Qt, got it running, had 15 weeks or so left to catch up (sync) when I purchased some bitcoins and had them sent to my new wallet.
Then to my horror, Bitcoin-Qt has frozen with four weeks to go. It has been running 48 hours without any change in changed blocks left. I have restarted my computer, rebooted the modem, all the simple things but no love.
What can I do to access this wallet? I'm new to all this. I only ever used my online wallet address before.
