Same here...Windows 7 Pro, GETFLV 9.8.185.18 and I can not download any Hulu movies.
It stops half way and I can't stop/restart the thread to continue downloading.
Tried logging in to Hulu, not logging in Hulu, Chrome browser, Safari, letting the video window stay open, closing it...nothing works.
Here's one to try

If there is a trick to getting it work, please let me know!! Thank you.
