Follow the steps below:
1): Locate the chatlog file (make sure it is in your Documents folder in the (C:) hard drive)
2): Right-click the file and select "Properties".
3): Make sure the "read-only" is unchecked.
If there is no "chatlog" file - try create one. Open "Wordpad" - add one empty line - save it as "chatlog" and re-try.
If the "read-only" is already unchecked and it is still not working - contact me on discord for live support.
