Getting message "menu?", need help for DSi/R4i

Hi for my DSi, had a R4i with a memory card (micro SD) configured and a few games from a knowledgeable person. Games used to work and all of sudden, it stopped working, once R4i is in console, game name appears for selection on lower screen, once selected, I get message "menu?" on top screen and it can not continue there after. Do not get list of games for further selection. Other game card works fine so DSi console is fine. Either its R4i or memory card issue. Any suggestion, what should I do, I have very limited knowledge in this area?
