Embedded Youtube videos missing - blank space

www.instructables.com/id/Lithium-Rain-Radiant-Beacon-of-Righteousness-Blin/ 

Previously embedded youtube videos are missing.  There is a blank space where the video widget should appear in the instructable.  2 videos are missing.   I also had embedded a video as a comment in forum topic "Why" and that embedded youtube video no longer appears.  The comment appears as a blank space.

XP, bug appears in IE and Safari.

update: FIXED. I needed to uninstall flash player and install latest flash player.  Security settings to allow video to run only on external programs seems to have been reset/changed in IE8 browser options.

appears fine in ff right now
youtube was doing maintenance, so i think that was the source of the problem

Hmm, seems my PC is afflicted with the Youtube upgrade/ Flash player/java incompatibility syndrome BSOD (blank screen of death).  I'll give FF a try in XP but it seems time for this machine to go Ubuntu. 
YES it is indeed time to go Ubuntu. :D

I didn't seem to have any problem.  Could it be that your internet connection was running slow.  Sometimes, when my provider goes all mental, my internet slows to a screeching hault.  This tends to not allow video.
