if 'PAUSED' is yellow, then your SHIFT is stuck down. hit & release it. you can also right-click to unpause the list
as for icebox, it's an auto-installer/updater we put together for oQueue and are starting to expand. the icebox addon coordinates with the icebox application.
you can get icebox here:
http://solidice.com/icebox
it's on the navbar at the top, click apps
My **PAUSED ** is in grey, gonna try uninstalling and re-installnig using icebox
