Boris FX plugin not showing up

Hello,

Can you share with us your pc specs?

and you can also try to do this workaround:try moving the set(s) of plug-ins that aren’t loading to outside of the plug-ins folder, then hold down Shift while launching to clear the plug-in cache.  The plug-ins still in the plug-in folder should okay.  Then move the problem plug-in set(s) back into the plug-ins folder, and launch (without holding Shift this time).  This means the plug-ins re-added will be loaded incrementally.  The plug-ins should load successfully in this case, and should be fine after that.
