I got an R4i Gold today. I stuck the MicroSD card into the USB reader and put it in my PC (running Windows 7 64bit). The divers install. The PC won't open it. I try a USB drive that has worked before. Now that one won't work. At this point, it won't even recognize USB drives any more. I try another PC (same OS). It just skips to the not-recognizing-USB-drives part after installing the drivers. I try my Mac. Works fine. I put the necessary files on to install the firmware. Once I load it on the DSi, I just get a loading screen. Then, I decide to try Wood. I notice that the free space does not increase when files are deleted. Apparently, the only way to free up space is to erase the whole card. Whatever. I erase the card. Try Wood. Same result. Please respond with help (for either getting the USB ports working on the two PCs or getting the R4i working, I don't care). Alternatively, respond with exorcism rituals.
