R4i SDHC not working on 1.4.1U DSi,, and won't work on DS Lite

I accidentally updated, and now my R4iSDHC wont work on Lite or i. On the DS Lite, the card wont show up on the menu. On the DSi, it's slow for it to show up, and I need to press it down a bit. Will I need to buy a new card? If a patch comes out, will I be able to play again? Sorry, I'm a bit of a noob.

there are many r4isdhc in the market. you have to be more specific. I recommend goint to the card's site to see if there is a fix for it. but it should work on dslite
