need help whit a micro sd card .. stucks in loading..

hi, i need some help whit this..
i bought a new cellet micro sd 4gb and already tried formatting and reinstalling the r4 firmware but stucks on loading D:
when i try whit my other Kingston micro sd 1gb it works perfectly what to do ???

If you have an original R4, then it is because your new 4GB card is SDHC. The R4 does not support SDHC (High Capacity).2GB would be as big as you can go. There are non-HC 4GB cards, but they are very hard to find, and the vast majority of 4GB cards available are HC.

They do have the new R4HC now that can handle up to 32 gig micro sd cards.Check it out here. http://www.thedsdeals.com/R4_DS_SDHC_p/iai165.htmI know that's not an answer to your question but I just thought I would throw that in there.
