Dolphin won't open.

[TomisOps]

I downloaded the latest beta version and it just won't work, I extracted it to a folder in my desktop and whenever I open it nothing happens. It wont open even if I open it with administrator rights. if i look at the task manager I can see it pop out for a second and then dissapear. Any help? I can run the latest "Stable version" because it opens, but i want the newest one.
