When you guys say it hangs, how long is it hanging for?
Basically you'll want to go through the troubleshooting steps in the first post here:

If those don't fix things, we'll need the following info (as mentioned in that thread).
So please let us know the following:
Are you on a PC or Mac?
What OS are you using?
Do you have the game on Steam, Origin or the Standalone?
If you are on a Mac, what specific model Mac do you have? Also if you're on a Mac please attach the Mac crash report that pops up after a crash.
What are your system specs (especially your video card and your amount of memory)?
Where exactly does your game crash? What are you doing just before it crashes? Can you consistently get the crash to repeat by doing the same thing or is it seemingly random? Do you get an error message? If so, what?
Does this crash in only one saved game or in multiple saves? If only one, then we'll need to see your league files as per the instructions in my sig (or you can just upload to Dropbox/Google Drive and post a link)
It would also help us to have the game generated trace file.
To generate that on a Windows PC, do the following:
If you're on Steam, right-click on your game in the Steam library, then Properties, and on the General menu click on 'Set Launch Options' and enter the word "tracemode" (without quotes.).
If you have the standalone, right-click on the OOTP20 shortcut on your desktop, click on properties and add 'tracemode' to the command line
Then try to start the game again. Get it to crash.
After it does so, navigate to the following folder: Documents\Out of the Park Developments\OOTP Baseball 20\debug
Find the trace file there and post with the rest of your information. That should have some data that will help us figure out why the game is crashing.
