I heard the wallet has been updated, how do I update my wallet?

**WINDOWS – invalid blockchain**

backup your wallet.dat file
most important
once you backed it up, back it up again to a different location (ie. thumbdrive)
then close your wallet (make sure the process isn’t running)
delete these files
then download the windows .exe installer
install to c: or where ever you installed your wallet to
add the pivx 3.0.0 to your antivirus exceptions
run pivx-qt.exe from your pivx-3.0.0 directory
let it sync
