Lightburn new version won't let me jog to fixed value

I updated the software to latest version, it reads the machine but I can’t jog when I put in a value of 0.5 inch, how do i go back to previous version? or how can i get this fixed?

Please see:

can you share a bit more info as to what machine you’re trying to work with? I’m happy to help you find a way to use 2.0
