Glo Calibre/Kobo Glo "error communicating with device."

Hi,

I wanted to add a book to my Kobo Glo via Calibre (As usual) but for some reason, Calibre stated that it is "error communicating with device."

I did a factory reset 3 times, updated Calibre to the latest version but nothing happens :( This is what the error in CALIBRE tells me:

But first to tell you the story, after the first attempt of synching with Calibre, my Kobo Glo acted weird since all of my books is inaccessible (all of them are DRM-FREE) but after the failed synch attempt, the Kobo IS looking at all of my Books as DRM so it is not reading them with an error "Oops! You cannot access DRM books blah blah" and all of my books have no covers in the Library. ALl of them inaccessible prompting me to do a factory reset.

I have a Kobo Glo version 2.6.0. Please help.
