So I spun my instance up from the web, downloaded a keypair installed it and everything worked great for about a day. Then I rebooted my computer, and I'm not able to SSH into it anymore. I tried redownloading a keypair and reinstalling it but I keep getting the Permission denied (publickey) error.
This is the verbose output (I've tried using the -i /path/to/keypair option as well with no luck):

I've also tried rebooting the instance. Anyone have anything else I can try? Thanks so much!
