Sexyshado, there is no automatic way but you can edit the file youself. Open eq2ui_mainhud_hotkey.xml in the ProfitUI folder with a text editor, search for
framecolor="#B5B5B5"
and replace with
framecolor="#000000"
wallofchaos, delete the file mentioned above. And you should be able to use the startbutton you want, the ProfitUI one is not required.
Both of you make sure to put the file on ignore in the updater if you use it.
