RetroArch stopped working Android 4.1

I recently downloaded this to my android 4.1 jellybean tablet. I do not have an SD card yet but I loaded sega cd games and the bios files to the download folder on the systems memory, every time I try to load a game of any core (system) I get the message " Unfortunatly Retroarch has stopped" I don’t know what to do or how to fix the problem, I just downloaded this off the google play market. any ideas on what I need to do to correct this? I really want to play Lunar on there.

I cleared the app data as well and it did not work to ix the issue

uninstalling and reinstalling did not work either

I now have an SD card I moved the bios and all my games over to it and still it does not work, every time I load a game it crashes with the message " unfortunately retroarch has stopped with the options report and ok

I don’t know anything about cfg files or anything like that, I have tried uninstalling and reinstalling and clearing app data, I just want to know if this is compatable with my android 4.1 or do I have to wait for an update?

Systems tested : Sega CD, SNES, Sega Genesis all with the same outcome
