Flat Mobile Joomla

I have just purchased Flat Mobile Joomla and got the following error "Cannot find XML setup file" 
I have Joomla 2.5 
how to solve this !

Do you install Flat package for J!2.5? (note that zip package you downloaded at mobilejoomla.com contains 3 packages inside, for J!1.5, J!2.5, and J!3.x)
