Fuze+ microsd card not recognized?

I have a problem similar to ones here. I have an 8gb fuze+ that would not recognize my 8gb micro sd card. My phone & wife’s phone recognize the card but the fuze+ (and my digital camera) would not. I chatted online with Sandisk rep, who tried various things but nothing worked. Sandisk REPLACED my fuze+ (within 1yr warranty) and the NEW one will still NOT recognize that sd card. I went to Radioshack and bought another 8gb sd card and everything was fine!!! Hopefully the firmware update helps everyone, otherwise take your fuze+ to an electronic store and explain that you’ll return their sd card if not recognized, & just try it right there:) Hope this helps.
