Capistrano tasks quit working

I was able to run my Capistrano task from inside RubyMine for a while, but at some point it stopped working. I get the input field to enter my task, I choose the one I want, and the dialog disappears and nothing else happens.

Note: I can run the same command from the command line with no problem. (This is the last reason that I need to keep a Terminal program open.)

I'm not sure where to look for an error message, and I'm not sure what the event was that preceded it not working anymore.

Thanks,
