C3M 21.2 - Adding New Fuel Crashes GUI

Hello, I am starting out with C3M and have found that the program crashes when adding new fuels. I have followed the user manual instructions available in the Help bar and ensured that the proximate and ultimate analyses match. After the crash, the fuel does not add to the list when reopening the program. Is there anything I can check on my end to successfully add a new fuel?

Which version of C3M and which OS? Thanks.

C3M 21.2 and Windows 10

I apologize for the delay. I have addressed the issue. I am just waiting for the updated versions to be uploaded to the mfix website. I will let you know when that occurs.

The latest version has been uploaded. You can download it here:

Thank you! I was able to add in the custom fuel successfully with this new version.
