R4 Malfunction

Hi Everyone, i have been using R4 for about 4 months now and it has been working fine.Yesterday however i managed to bang my DS against my Bedroom Wall.Now whenever i attempt to run my R4 i get a black screen with the messge SD/TF Card ErrorI have tried my DS using other games and it works fine, however it will not run my R4.Any help or suggestions would be great.

Lol i think ill get in before you get flamed about R4's being rubbish(which i can assure you they are not)
Youve proberly broke it then, try formatting the Memory card first and then but all the software and games back on it then try again.
If it still dont work, i would buy a new R4(III is absolute awesome)Hope i helped ;)

try taking the microsd card out and putting it back in, it may have been knocked out of alignment with the contacts

thank you both for your help

it sounds like your microsd has died, try replacing it.

Can You suggest me which microSD is best to use?
