[Plugin: VideoPress] – iframe not loading

using the VideoPress plugin, and when i try to add video on a post, the iframe that pops up is just plain white.

if i logout of wordpress.com, it shows the login, but does not do anything when i try to login.

tried it on 2 different WP installs 3.0.5 & 3.1.2.

VideoPress subscription ends on 5/18/2012.

please help.
