Grandia issue

Hi all
I've just moved my ROMs and memory card settings from my Samsung Galaxy S5 to my external SD card only to find the memory cards no longer work. I've transferred back. On both internal phone memory AND SD card (I have them on both now) when I run the bios I can view my Grandia save file yet when I run the game itself it comes up with No Game Data.

Please please tell me how to fix this. I was so far in!

after starting the game make sure the correct memcard image file is still selected for slot 1

also make sure the game and the save are from the same region & the same version
