Additionally, when I run simplewallet, it says "Starting refresh" then hangs for ages and then says:
Error: refresh failed: no connection to daemon. Please, make sure daemon is running. Blocks received: 0
I don't really want to start again and download the whole blockchain. Can anyone help with troubleshooting these issues?
So, you have stopped it and restarted it?
You shouldn't have to download the entire blockchain, as your computer should have stored up to the point where it got stuck, or at least somewhere near that point.
Others (Devs maybe) can possibly be of more help, but it will assist them if you tell us what Operating System and which version of the daemon you are running.
