G'afternoon Tiburon and welcome to the forums!

when you get that message, it means the region name specified in the command does not match any region specified in the maximizer layout.

go to keyclone/setup/maximizer and look at the region you want to place the wow in. check the region name.

then go to keyclone/setup/command-editor and click on the command in question. compare the region names. make sure the region name in the command match is correct.

also... make sure 'enable maximizer' is enabled
