Published project quits unexpectedly?

Hi,

I've recently came across this problem. I'd have published my game on unity for mac osx (standalone) and when I open the built app, an error message pops up claiming that the app has quit unexpectedly. The funny thing is, this recently started happening. It's not only with my recent builds; it's also happening with previous test builds that used to work before this problem woke. I don't know where on earth it came from. I even tried opening the app from the console using "open (path of file)" but I only managed to get that working once, after that, it suddenly chose to quit unexpectedly again - I don't know what the hell that means. I tried to open one of the earlier back up versions of the projects before the problem occurred and tried building my game from there. Unfortunately, I had no luck and the problem persisted. I even tried re-installing Unity, but, again, no luck.

The first time I noticed this problem was when a pop up message came up after I tried opening a recent built game from unity, this is what it said:

So I ignored it and clicked Restore Windows (I don't know why) and suddenly this error message came along:

Now, no matter how many times I open my game, the first error message would appear for about 1 seconds and it would instantly go to the second error message, which reads "(app) quit unexpectedly." and with a bunch of random writing explaining what the failure was, which is quite pointless since the User is most likely not going to be able to understand it. I tried opening other apps from the app store and they work absolutely fine. I even unchecked "Restore windows when quitting and re-opening apps" under general in the system preference, but still nothing.

My head is going crazy, any help would be much, much appreciated.

Thank you for your time.

ps. I'm using Unity pro version 4.
