Ok Have a major issue here regarding my Kobo Touch. I have a lexar micro sd card 8 gigs in size. Since I have done the upgrade to 1.9.12 and reformated my sd card I can not load any books from the sd card. The card shows up correctly as a drive when the kobo is plugged into the computer. The books are all there, they just wont get recognized by the kobo. Also calibre ignores the books on the sd card as well (sorta hoped it might pick them up

, but kinda figured it would not). Not sure how to sort this one out. The card was 100 percent fine from day one. Any suggestions? Yes I have tried to go back to an earlier firmware can go back as far as 1.9 but not to the original fw on the touch. Any suggestions would be helpfull.
ADDITIONAL information:
I should also point out that the reader would recognize the sd content on a full power cycle and then after reading a few pages or paragraphs it would dog ear the upper right corner and suddenly my book would close and the only books showing on my list would be the ones in the main memory of the KT.
