Please Help

Thanks to work over the last year or 1/2, I have not been able to play on my DSi.
Last week Pokemon White/Black came out and my friends wanted me to play, however when i tuned my DSi on it prompted me for an update and I did. Now however i no longer works, my R4i has been updated to 1.31d, which i think is the latest one, but it doesnt work. I have the R4i not the version 1.4 or 1.4.1 or whatever! Can anyone please help me to make it work? I really dont reel like ordering a new one!
Thanks in advance!

if your flashcart does not have an update to defeat the dsi 1.4 update then you either get a new flashcart or do without.
