Heres what I tried now... Reset device, connect to computer and reformat it to FAT32 (not quick format), reset (reinitialized) again just incase.... started calibre and pluged in the device...
All good, no errors. tried to send a pdf to the device and then:

calibre, version 1.46.0
ERROR: Error: Error communicating with device

[Errno 13] Permission denied: u'G:\\metadata.calibre'

Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 86, in run
