Pm me and let me and let me know how it goes. :)
I have the 64gb card and it does get tricky sometimes. I found that there is a correlation between the format of the card and what ROM you are runniing on the device. Stock does not like the default exFAT format of the card so if you change it to FAT32 it should work. Or you can flash something else that will play nice with the exFAT formatting like Beans Custom ROM.
