FIXED: I just reinstalled Action! It now works. I don't know why it did this in the first place though.
I click on Action! and it asks me if I want to allow Action to make changes to my computer. I click yes, nothing happens, and then the application closes. If I alt-tab it doesn't show the application, running as administrator doesn't help either. I checked task manager to see if it was running, it wasn't. I restarted my computer as well. I don't understand what the problem is, please help.
