card on my infinity tablet

Solution
Could you please tap the Apps square, choose Settings and About Device then post back the version of Android you're running.

If it's the most recent versions, you may have to nominate whether to use the card as Internal Storage or Portable Storage but if you choose Internal, some Apps may not work outside the system file locations.
