Clipbank and ocget.dll despair

[El_Nombre]

Hi helpful guys and gals...

Absolutely out of ideas with this one. We bought Clipbank a little while ago and, with no recognisable patterns, a few machines just aren't playing nice with it. Have put the shortcut in Ranger, Windows Media Ruiner, I mean Player, is installed and working on the machines. However, when a teacher logs on and tries to play a video file the little flash preview works fine and with sound, but actually clicking on it to play the video itself opens the page and spits out the error message:

"Windows has blocked this software because it can't verify the publisher.
Name: ocget.dll
Publisher: Unknown Publisher"

And then the video plays but with no sound.

So, I go into Ranger Admin for a rummage and under the All Computers policy I elect the option to allow ocget.dll. Log back in as a teacher and same old message and no sound still. BUT this doesn't happen as administrator; entering the IP address of the clipbank server to get into and play the clip it all works just as it should.

I'm stumped with it so I thought I'd see if anyone had any ideas. Something in Group Policy I've not seen?

Thanks in advance for reading.
