Hi mike,

> After installing 3.1 how do I get the custom interface back?

You have to copy over the same files into 3.1 that you did with 3.0 .

In this case since there were no changes in the UI from 3.0 to 3.1 you can copy over the entire UI directory from your customized v3. To do that right-click on the MoI v3 shortcut and choose "show package contents". Then inside there go to drive_c/moi/ui . Do the same thing with version 3.1 , then copy all the files in the v3 ui directory over into the v3.1 ui directory overwriting the existing ones.

If you have installed any custom commands in the commands folder previously then you will want to copy those over as well, from the v3 commands folder (drive_c/moi/commands) to the v3.1 commands folder.
