unomunts but never remounts

My SD Card is unmounted when the Mac goes to sleep, but once I wake up the MacBook Pro (with El Capitan) the card never gets mounted again, not even ejecting it manually and reinserting it. I need to restart everytime this happens. There is nothing on Mountain’s web page or on the FAQ to solve this problem. Usless app, don’t waste your money.
