External Plugins suddenly stopped loading.

Trying to add an external plugin to a VST plugin slot and nothing is happening. Both audio tracks and group. tried deleting the external fx and re adding. nothing.

I realized this is because the external plugins I was seeing, were old ones that were still added in my plug in manager user template that were no longer legit. so i had to delete the ones in my plugin manager temp and then re add them. I figure external plugins should be separate from user plugin manager?
