Use calibre and Windows 7. Recently got a Nook HD+ as an early Xmas gift and was loading books onto it from existing Calibre selections. Things were going smoothly then I started getting an error message.

Traceback (most recent call last):

File "site-packages\calibre\gui2\device.py", line 85, in run

MemoryError

I have the 32gig Nook and also use a 32gig Scandisk micro SD card in the memory slot. Only seems to affect the books I have recently added to Calibre. Can anyone advise on how to correct this or even what it means? Tired several easy/quick fixes but am not as computer literate as others and thought maybe someone else would have an idea.
Thanks for any help
