MemoryError
 

Brand new forma out of the box, I added books then got this error after books loaded and metadata was being updated (this is where the error came up. I then ejected the device, retarted it. The forma then started back up with the new introduction/customize screen as if starting it for the first time (wifi setup/log into account etc) I went through the process again as I did initially did. Then a adding books screen came up and when it was done no books where on the device only empty collections of the books that had been transferred originally.

I restored to factory defaults and did the whole process all of again and restarted calibre added books and it again same thing happened except this time when I restarted the forma and plugged it back in to sync it to calibre after 15 min of reading books on device it also came back with the same error. What I have tried is to change USB cables, USB port, did 1 book, did 50 books, over 2k books. I did a windows error checking on the forma (no errors)
My question is this a DUD and I should send it back or is there something else going on between calibre and the forma and maybe KoboUtilities?

Thanks for an information you might have.
