Query: No longer works after ~6 months

I have loved the blueproton mircoSD reader up until today because it no longer works. I have been storing it in a watertight pill container keychain and it looks brand new with no superficial damage. I have been using it along with a 32gb microSD card (the SD card works fine in my cell phone). I was using it last night with no issues, but now when I put it into my USB port I get nothing. The USB ports are fine, so it must be the reader.
