sorry guys that so bad.... 

Dimension Pro was released in 2006. It was updated 5 times. Development stopped some time ago. This year a replacement for Dimension Pro and Rapture was released called Rapture Pro. It is a paid upgrade and plays Dimension Pro and Rapture programs in addition to new content. A trial version is available http://www.cakewalk.com/P..cts/Rapture/Try-Rapture
