Try a different adapter if possible. You can find them at your local store, and they are usually cheap.Or you can go into your device manager and try to find it and uninstall/reinstall it in case windows screwed up.

where can you buy a new R4 usb????

Most electronic stores will have MicroSD readers/adapters. Otherwise a regular multi-card reader should support MicroSD.
