For Windows users to have the Tab Effect working correctly you should install Direct X 9 or later, you can download it here: http://filehippo.com/download_directx/. You May Also Have Issues and comp ability problems since this version is still in Beta Stages!
For Linux and Mac User the Pack is the 100% compatible, but the tab effect won’t work since it needs direct x, a Version for the OpenGL is in Work.
