I've been using Bitcoin Qt on my work computer (my only working computer at the moment) but last week Windows 7 decided that the program's bypassing the firewall to download the blockchain was a security risk and blocked it from doing so. I'm not the network administrator and fiddling with the firewall settings I can access hasn't done anything. While it is absolutely possible that I am missing some obvious solution, I've given up on fixing this. what I'd like to do now is download another offline wallet - one that does not need the entire blockchain - and import my Qt backup. I've tried MultiBit & Electrum, neither of which seem to work (although, again, it is possible that I'm missing something). Is there another program I can use? Should I wait until my laptop is fixed and just re-install BTC Qt on that? Am I out of luck?

3) and then you can just export any of the keys you need, using:
If you don't have any password over your wallet, just skip point 2.
