I'm using Eclipse Indigo with aptana, to develope a rails application and it was working fine, but now it keeps crashing on startup. It opens and when the loading bars appear on the status bar, it goes gray (not responding) and the in closes without an error.

Here is the output from the terminal when I ran it from there:
