Help! I usually play on my Mac using porting kit but it's stopped working!

I've tried everything I can think of:

• changing porting operating system
• trying different versions of porting kit
• deleting and reinstalling porting kit and AOE2
• crossing my fingers
• etc.

But when I open up AOE2 I see the steam window, but when I click "Library" I just get a black screen inside steam so I can't see any games, and can't open AOE2. I think it might have something to do with an auto update on my computer.

Is anyone else having this problem, has anyone been able to fix it?

Yes, I know it might be funny to you that I play on a mac, but I just want some help so my game will work. Thanks! :)
