Reinstalling the PG DirectX Plugins will probably fix it. You can find the installer in the bb folder:
C:\bb\Data\Installers\pgdx_plug_64bit_2_0_0.exe

The plugins (64bit) are installed here:
C:\Program Files\PowerTracks DirectX Plugins

To specifically restore the default PG presets you could run, this (but shouldn't be necessary)
C:\Program Files\PowerTracks DirectX Plugins\Save-Restore Presets\RestorePGPluginPresets.exe
