@ninjagull I would like help you but i fear that this Community will not succeed to provide you a solution. Anyway  for privacy reasons we can’t request Logfiles.

Thank you.  I do not have a paid for product!  Is there a community forum where I can possibly get help from other users?


Many thanks
