Just tried it but got error:

File "/opt/AutoCompleteEditor/AutoCompleteEditor.py", line 17, in <module>
w.loadData()
File "/opt/AutoCompleteEditor/ACE_gui.py", line 157, in loadData
self._dict = ACEFile()
File "/opt/AutoCompleteEditor/ACE_file.py", line 34, in __init__
self.read()
File "/opt/AutoCompleteEditor/ACE_file.py", line 119, in read

Wasn't able to catch the whole stuff.
Any clue?
