I have downloaded STO from steam and I have it on a desktop and a laptop.
My laptop runs the game fine, however, I cannot launch the game on my desktop.
When I launch the game from steam, the bottom icon shows up the blue windows bar, but nothing happens on my screen.
I've cleared my cookies and also made sure that I do not have a proxy Lan setting. I'm also not behind a firewall so that can't be the reason why its not loading the launcher.
