Symptoms
    Your PIVX wallet software does not start.  When you try to run it nothing happens, an error is displayed, the window disappears, the loading window never completes, or another startup issue is encountered



Cause


   An abnormal exit of the wallet could result in corruption of your local blockchain cache. This can happen due to a power loss, unexpected reboot, OS updates, or if the local blockchain cache becomes corrupt by other means.



Resolution


Method 1

  1. Make a backup of your wallet.dat file and zPIV seed (Best practices)
  2. Make sure you are running the latest PIVX Core software
  3. Try using the -forcestart startup flag to see if it will recover from a failed start.
        In the Windows GUI, you will need to make a shortcut to the pivx-qt.exe file
       

    Then, edit the shortcut properties and append it to the end of the "Target" field, so that the end reads:pivx-qt.exe" -forcestart
     


    From the command line on all operating systems you can call the pivxd daemon with the switch -forcestart



Method 2

    If Method 1 does not resolve the startup issue, try to resync the blockchain using the steps in this link
