So that is suggestive of something wrong on your end. As Ron's and other's experience indicates, 15-20 seconds is typical. It isn't airspace -- I am indeed loading the entire airspace of the US on startup, and mine is loading in about 20 seconds.

It probably isn't any firewall or security software, because it starts eventually. It isn't just blocked.

Here are some possibles, but not an exhaustive list by any measure.
- Not enough RAM on your computer. If this is the problem, it would be characterized by a crazy amount of hard drive activity (assuming you don't have a solid state drive) during the SeeYou startup as the system tries to swap memory pages to meet the demand. If you have a hard drive activity light, it would help determine this. It might be blinking furiously, or look as if it is stuck on.
- A dicey network connection. Have you been able to try it while connected to a different network?
- Some malware running on your computer, stealing resource. This could be characterized by high CPU, network, or disk usage during the startup.

If you have the skill to monitor the process using Task Manager or some other similar tool, that would be the next step.
