If you cannot launch Project Nimbus, it's very possible that the cause is just simple that the game's file is broken from some error in downloading/patching. Don't worry, this is very easy to fix.


1. Head to the Library section inside your Steam program.
2. Right click on the game's name to the left side ("Project Nimbus") and from the drop-down menu, choose "Properties"



3. Head to "Local Files" tab, and click on "Verify integrity of game cache" button.
4. Wait for Steam to check the game in your computer and download neccessary files. After that, close the Properties window and try starting the game again.

If that still doesn't work, try delete the game from local harddisk and re-download the game again.

Hope this help.
