I have split your post into a separate topic, as your problem is different from the other topic.
In Firefox, Tools | Add-ons | Plugins, do you see Shockwave Flash 11.5.502.135, and is it enabled?
What files do you have in C:\Windows\syswow64\Macromed\Flash ?
Enabling did it! I do feel like a fool, but what can I say. I've done so many dumb things in the last few weeks I'm getting used to it. On the upside, it's not likely I'll do it again.
Have a great new year in 2013,
