Previously I had the official windows desktop ethereum-wallet synced and working, but the other day my computer crashed and corrupted my blockchain sync, so I deleted my chaindata folder and started over. This time I synced with geth --fast --cache=2048. When it was caught up I closed geth and attempted to open the wallet, but ever since then I immediately get an error that says something like "Unable to connect to node, see the logs for more details." I made sure I was allowing geth to communicate through my firewall, but that didn't fix anything.
My question is, where are the logs and how can I view them? Also when running geth --fast, what is the proper way to close geth once it is caught up? I used CTRL-C in the command prompt because I couldn't figure out a better way. And for future reference, can geth --fast be stopped before it's caught up and then resumed later?

geth --fasthas nothing to do with the connection to node,--fastis only tellinggethto sync the block headers only and enough to perform transactions. A few latest blocks.Wait until the node is fully synced.
