Help!

Hello. I'm finishing my gunz server. I used Phoenix's repack 3 server flies and client. If i start Gunz with "Test runnable" (it comes with the client for test) it works, but when i download other runnable (Phoenix's runnable too) it doesn't works, i do double click on it, and it doesnt open. Help?

PD: Sry for my english, im argentinian :(

Serial key is enabled on all other runnables. You need to launch GunZ via a launcher.

Thanks.
