The Logs folder isn't script related, but it's required. __init__.py isn't needed on it.
It is there just for GravityFX to dump logs into it, that's why when i packed GFX up i left it empty, why would i send you a log with the install? lol
But the .exe installer doesn't create the folder, probably because it is empty...
Also, creating .txt files in it isn't necessary, the Logger creates them if they aren't there, the only problem is if the folder is missing, because it doesn't create folders. And that is exactly what happened.
Now, what is REALLY strange is the TimeMeasurement *supposed* bug, supposed because i have it here, working, exactly like i put it in the pack, and all made using tabs, no spaces... Plus the console report DOESN'T tell what error happened in that line (you know, AttributeError, ImportError, etc...)
