Windows .exe Unleashed...Crash? Error?

[QuantumNexus]

So I downloaded the [1.5.2] Unleashed Pack from the FTB Launcher, and was ready to play. However, when the download was completed, the pack didn't load. Minecraft never showed up. Even when I exited the launcher and tried again, same thing, no avail. Anyone know what's happening?

More info: When I click "launch" on the Unleashed pack, there's the brief flash of the "Downloading Mod Pack" in the top left corner, and then it seems as if it would launch, but just doesn't.
