Mac OS X Mavericks Editor problems

[Corvo]

Since I updated to Mavericks its occurring an error whenever I try to open any of the editors, my game works fine, just the editor don't work properly.

FATAL ERROR: Could not load vertex buffer from mesh 'core_box.dae'

I already reinstalled, and the error keeps showing up, there is an patch or something to solve this error? I really would like to keep doing some custom storys

I had the same error not long ago, when I wanted to run two Level Editors at once. Because I got this error trying to load the Level Editor while another instance was running, perhaps make sure that no other Editor process is running.

Not sure if that will work 100% though.

@Romulator

I am having the same issues and have tried everything and no luck so far. I am hoping its because they have to update it or something. following this post in hope someone figures it out
