I'm not sure if the issue at hand here is that the window itself is not opening (which, like Faetyl said, is most likely due to a corrupt window placement file), or if it's that there aren't any buttons/icons showing up in the Persona window.
When I originally had issues accessing the reuse timer window, that was due to the latter of the two. And for some reason, the AU did not update the Persona window file for me ( and no, Faetyl....it wasn't because I was using a 'newer' file than what the AU supplies. I've used the same window the AU has in it since day one
). In any event, I managed to remedy the situation by deleting the Persona window file and pulling a new one down.
Not sure if any of this helps, but there's my 0.5cp (I'm too poor to be able to afford the whole 2cp
)
