Buggiest software I've ever had the displeasure of using - coediting broken, can't publish, no specs

Everything was great... until I tried using coediting. Yes, I understand it's still in beta, but it does not work even a little bit. I added one other person to a file, and every time one of us opens the file while the other is in it, the person already there gets an error and it crashes. Every time a new update came out, we updated, hoping it would fix the bug, but each time, it got worse. Now, in addition to coediting not working, I can't publish my file. Every time I go to update the link, it takes ~1 hour to get to 99%, and then it tells me there was an error. Not only that, but my spec links no longer display the specs tab! I have had dozens of developers at may desk day in and day out for the past few days asking for specs and updates over and over and over and over. I now spend a majority of my day trying to open and publish files. I can't get anything done, and the project I'm working on is coming to a standstill with nearly 50 developers idling while they wait for updates.

The only thing I can figure for the update issue is that the file has gotten too big. I only have ~160 artboards and have been trying to delete unused ones, but this project is easily going to get up to 500+ artboards in the next few weeks. At this point, these issues are threatening the business initiative I am currently working on. This is about to cost my company millions of dollars if it isn't solved soon. Someone please help!
