went to Couatl.ini...opened...
only thing in it was...logfile=etc,etc.
You are assuming here you are supposed to see other things in the .INI file, but that's not what the .INI is used for. You use the .INI file to enable logging, that's it.
If you do it correctly, when the program starts, you are supposed to see A NEW FILE, called Couatl.LOG, in the path you specified there. In fact, I suggest not adding a path, which will only increase the chance of mistakes, instead, make the line as simple as this:
logFile=Couatl.LOG
which will create the Couatl.LOG file in the current folder, the same with the .INI you edited.
If you still don't see the Couatl.LOG file, it means the problem is REALLY the antivirus, because if it blocked it, it blocked the log creation as well.
