Okay, so my SD Card decided not to work on my R4 anymore. It stays on the loading screen. So I thought I just needed to reformat the SD Card. So I download one of the formatters on this site, and I tried it out. But then it said that the Driver isn't supported. Heres a picture. I also tried formating it by right clicking the drive and clicking format. But that doesn't work either. Do I have to buy a new SD Card? If I do, how much do they usually cost? Or can I fix this SD card? I need some help from you guys, because I obviously don't know what to do at this point. Please reply as fast as possible! Thank you.
