Covergloobus not launching

Hello!

I'm running Elementary Luna OS

I can't launch Covergloobus.

Launching from the Terminal I get:

core.settings:WARNING: Configuration file not found
Traceback (most recent call last):
  File "/usr/lib/python2.7/logging/__init__.py", line 846, in emit
    msg = self.format(record)
  File "/usr/lib/python2.7/logging/__init__.py", line 723, in format
    return fmt.format(record)
  File "/usr/lib/python2.7/logging/__init__.py", line 464, in format
    record.message = record.getMessage()
  File "/usr/lib/python2.7/logging/__init__.py", line 328, in getMessage
    msg = msg % self.args
TypeError: not all arguments converted during string formatting
Logged from file covergloobus.py, line 79

I had previously tried to edit a theme and obviously ballsed something up :/

The message and problem persists after purge and re-install

Oh and I don't have a clue about Python!

Any ideas?

Thanks in advance
