I just finished my first game on 0.C Cooper, and I’m trying to start a new one using 0.C 4011, but the game don’t load at all. It just hangs in my task manager, and I’m unable to end the process.
Has anyone else had this problem? I’m using Windows 7.
On a side note, is it possible to replace the keybindings.json file with the old one I used in 0.C Cooper? I made a lot of changes to the controls and I’d prefer not to have to do it over again.
**Had to disable Avast Antivirus, works fine now!!**

Isnt there a thing about using avast and this?
Also try loading an earlier experimental.

I just disabled Avast, and it works like a charm.
Thanks!
Can I put my keybinding.json file from 0.C Cooper into experimentals? I don’t want to have to redo all my keys again.

yup, psure you can.
you can also add an exception to avast to allow cdda to run without disabling avast
