So recently I downloaded the new Hitfilm 3 Pro, and I immediately tried opening it after it had downloaded. However, when I went to open it, it would start bouncing on the dock bar (I have a Mac Air) and then would randomly shrink down and close without a trace. I can't figure this out, as I have all the files downloaded, the plugins, and everything. What is worse is that I cannot delete it from my laptop now that it is on here, it just won't let me select it for deletion. Could someone please help? I really loved Hitfilm 2 and was psyched to download it, but now I can't make it open. P.S. I do not have a paid version, I used the free trial for Hitfilm Ultimate 2 last year and tried doing it again this time, but when I click that in the plugin application, it vanishes and nothing happens.
