A problem caused the application to stop working correctly.

I'm working on a rather large project, and I had this notification pop up when I tried to reopen the project.

"A problem caused the application to stop working correctly."

After trying to find a solution, uninstalling and reinstalling the application several times, installing and trying to use previous versions of the application, and reupdating the application I finally gave up and started the project over. I had a good week's worth of work into it the first time, so I stayed up late restarting the project. All was going well. Decided to save it because things were starting to move slow. Closed the app so I could catch up on a few other things. When I try to open the new project, same error...

Now neither version of this project will open. I can't seem to find a way to convert what I have done to a different file format to keep working on it and at least salvage what I've done. I don't know what to do and am getting extremely frustrated.

1. Use the Creative Cloud Cleaner Tool to solve installation issues

2. It can depend on your project file size and hardware. What is you hardware and RAM?

Here are my specs. The file is only 1.4 GB which I feel should be manageable. I expect it to run a little slowly, but I can't even open it right now.

16G Ram is small for a Mac + most apple people love to have 15 different tabs open to really suck up their Ram while working... have you got a pal with a better system [i.e, more Ram] that can help out?

LOL 16GB is small,  yes I wish I could have more than 16GB ram installed.   I believe a MBP goes up to 32GB now?  Is that correct?  Or did they jump forward and now you can get 64GB?   (the latter would certainly make 16GB small.  But for Adobe Dimension, if it can't operate with 'only' 16GB RAM, they're doing something wrong!)
