When I start Pro Tools, it says that Band-in-a-Box DAW Plugin "failed to load because it is not a valid 64 bit AAX plugin"


The most likely cause is that you need to update your iLok software. Open the iLok License Manager and go to Help | Check for Updates - download and install the most recent update, and then reboot your PC. An additional tip is that you can have Pro Tools rescan your plugins by removing (or renaming) the file C:\Users\<username>\AppData\Roaming\Avid\Pro Tools\InstalledAAXPlugIns
