Yep, I just happened to chance upon that revelation yesterday. Turns out Window Blinds doesn't play well with Action at all. Dang.

3.10.2 is working now though, gonna try 4.6 again.

Thanks for your time!

No dice. I've already uninstalled, deleted the registry key, restarted, and reinstalled to no avail. I also uploaded a video to show what my problem is visually: https://youtu.be/HdTEa-3FH6Y

Of course, I ran DxDiag again for you too.

Sure thing, here ya go

Just like the topic said, it's crashing on startup. When I try to open it, an incomplete version of the UI appears for about 10 seconds before it just completely dies. I tried the uninstall thing from the FAQ on 4.5 and it didn't work, and I'm about to try it again on 4.6, but my expectations aren't...
