I think I'm getting a similar problem, though deleting and reinstalling hasn't helped. It crashes instantly and when it prompts me to reopen it gives me the error message "Failed to find locale/en-US.ini" and then "Failed to load locale." It was working fine earlier yesterday and then all the sudden I tried to reopen it and it stopped working. I didn't notice that it closed improperly the last time I used it.
EDIT: I had to go directly into my Library and application support to delete a few other files but it seems to have finally reinstalled properly.
