Hi rgubele

I am sorry for your issue, let's go and fix it. Kindy export the Tech-Support file out, you can simply go the web GUI, Maintenance \ Export \ HTTP File Export \ and select Tech Support at the end of the drop down menu list.

You can use the private message here to let me know where I can get that file, and we'll be able to assess where is the problem.

Thank you,
