Nothing happens when opening dolphin

[Monochrome]

Kind of new here (been lurking), I've read everywhere but I simply gave up. I don't know what to do anymore.
I've downloaded Dolphin 3.0, installed it nicely, then, when attempting to open.. Nothing!
It simply does nothing. No error, no glitches, no nothing. Attempting to open it again doesn't do anything. I simply don't know what to do.
I'm using Windows 7 32bit.
Trying to download the newest rev also yielded no results D:
However, dolphin 2.0 works (I'm really not experimented in these kinds of things).
Any help in getting 3.0 to work?

Does anything pop up at the bottom on the taskbar?

Nope, nothing.

So, nothing? D: Sorry for double posting, but this already fell to the second page and there's still no solution :[
