Format it to FAT32. I had the same problem, and I thought there was something wrong with the memory card so I went out and bought another one. Before I formatted the second card, it was fine, but then when I formatted it to NTFS i got the ';memory card is not inserted correctly'; message again, so I reformatted it to FAT32 instead, and it works fine now. I also did the same for the first card, and had the same result. Hope this helps.
