Had some trouble with the AIR-Library too.
(Using PPRO2010 SR1 on W7 64bit Ultimate)

4 days ago, i could not anymore bring the AIR-libray back to screen.
the window was there "minimized" in the taskbar, but clicking on it had no result,
except a short flashing.

Besides the AIR-Library i  use D3D's XL (prefered). So the evening the problem appeared i did'n care much about it.
Turning on my machine the next day the problem was still there.
Yeah, hunting time for the Scorpion (=Me).

With my experience, i know that often wrong settings in the initial files causes problems.

Found that:
C:UsersUserBAppDataRoamingLSMGUIAIR.64AAB1E9DCCE40D96A4E881F8BD26884D826DB32.1Local Storepreferences.xml

WITHOUT RUNNING POSER!
Deleted "preferences.xml" to recycle.bin for eventually later restoring, if things go worse :)

Starting Poser after that, my AIR-Library loaded normaly again.
And srry, i could not reproduce the error until now.
but the library still works fine :)

Maybe that coud help 

BTW: i only once answered the qestion to windows wether poser has access to "internet"
or better said ip adresses in the local network, shortly after installation. Since that i had no probems with that.
Disconnection my local network from the internet has no influcence on how poser starts - wether its connected to the internet or not.
