This is due to a change we had to make in 6.01; to fix it, uninstall Sapphire, delete any DissolveLensFlare, LensFlare, LensFlareAutoTrack, Glare, DissolveGlare, Flashbulbs or DissolveFlashbulbs effects in your project, and then reinstall 6.01.  If you changed any settings, please re-install Sapphire v6.0 and save a preset.  Once you've done that, delete all affected plugins and upgrade to Sapphire v6.01.  This incompatibility was unavoidable and we're sorry for any trouble it causes.
