You can replace lines 53 to 56 of userinterface.py

Code:

try:
       open(os.path.join(ADDON_PATH_PROFILE, 'cookies.lwp'))
    except IOError:
       login()

with

Code:

login()

This forces the add-on to login on everytime you start it. It doesn't really fix the actual problem but this way you won't have to reenter your login credentials each time. Make sure that login() has the same indentation as the try and except or it won't work.

This tweak seems to have worked for me, have not had issues for 2 nights now.

Thanks Carb0!!
