Can't save config

[GuitarGod]

Hey Donald,

Just did a fresh install of Windows. When I try to save my new config I'm building I get the following error:

See attached

​Drive J is not a drive but my Windows User folder.

What can I do to get it to save properly as I already configured and lost my work several times?

Thanks,

What do you do excactly when you save your new config?
