USB stick problem

  • Just had wierd thing happen I just did update to Beta 2.3.3 and that went fine.. Mounted my USB stick back in my computer, then loaded some profiles I wanted to try , put the stick back in the KPA and this time it said the stick needed to be formatted. I've successfully been using this stick for a year with no issues, this one I dont get Any one know what could have happened to the formatting, when I put it back in the computer its ays the same thing "needs to be formatted"
