object reference not set to an instance of an object spam

[Lockaroonie]

Whenever i try to activate the overlayplugin.dll, I get spammed by a window with that message popping up over and over and over again. The plugin has been working fine for months and only suddenly has it stopped working.
Here's a log of what happens.

I've reinstalled act many times, and downloaded the full package of the overlay plugin many times, and still that pops up every time I try to enable it. Help anyone?

how'd you fix it?

[Lockaroonie]

ah sorry, its silly to end a thread without writing the solution. I believe the way I fixed this and similar issues is i uninstalled the program entirely, including all saved settings, restarted my computer, then reinstalled the program. simply restarting the computer without reinstalling the program might work too, give that a try first so you don't have to lose all saved settings and stuff.
