R4 Upgrade Revolution for DS FIX?

I have a R4 Upgrade Revolution for DS (NDSL/NDS)
My old games work but when i try to put new games on it the new games load you on a white screen which does not go away. also i have a 4gb micro sd HC class6 card in my R4 card.
once i switch my ds on everything loads fine and it says on the ds screen R4III english version, R4 III Revolution for DS v3.11 and loads fine with all my old games but no new games work.
I have tried updating the firmware but when i do it does not even load up the R4 menu so i go back to this firmware which does load up the menu and my old games.
can someone please help me so i can play the new games on my card?

Thank you
