could be nuespl's formatting process. When I tried installing nuespl I first tried using a non-HC card formatted by windows. It didn't work, so I formatted it with nuespl and it worked. Then I tried using the card in another non-PPC phone and the card couldn't be read. So then I had to format the card again using the other phone and it worked. So maybe try reformatting the card in windows or another phone.
