I'll start up Phoenix, it asks if I want to update, I say yes...it begins to update, I can see the progress bar in the lower right hand corner....I usually just fly for a few minutes while it's "updating"....once the progress bar is completed, I click on "Install"...it asks for my permission and I approve it...then a gray colored window comes up and says that it's waiting for a clear channel (or something like that, I don't remember. It's been a while since I've tried it).
I've tried dropping ALL my firewalls and that doesn't seem to help. I think there is something wrong with my PC that is not letting this happen.
