Closed Nightly Won't Launch

Whenever I click "Play" to launch Starbound Unstable - Nightly on Steam, it says it's running, but nothing pops up. About 5 seconds later, "Running" no longer appears, and it hasn't opened. Is there any way to fix this? I'm sure there is, but I can't find it.

 

I'm on Windows 7, I've done everything that other guides said always work, but nothing works. I even validated the files and they were all correct, but it didn't work.

 

I haven't been able to play from the launcher, but running the game straight from my windows64 file seems to be working.

 

That won't work. I said I've tried everything.

 

There isn't even a crash log to post, there's no starbound.config, there's nothing in storage.

 

Update: Now there's stuff in the storage, and there's some more stuff. Maybe now it might work if I do something.

 

There's a file named packed.pak, and it says it contains 767,376 KB....
