[CRASH] Unspecified error

So it was after school on a friday and I wanted to league. I clicked the icon and the first thing I notice is the fact that the client didnt even start up. Only the logo came up and it said "Unspecified Error, please check logs for more information."

Oddly enough, three of my friends experienced the same problem. But some of my friends said their league works fine. I even tried it on another computer and it works fine. We're all using macs by the way (please dont give me your Use a Windows bullshit I don't own a windows and thats that.)

It works however when we use this application that removes any firewalls or something that blocks certain websites. It's slow as hell though.

I don't know if this is a error common in most players but It is currently occurring to me and my peers.
