i've gone through switching the proxies, but in either interactual player or windows media player it just says 'acquiring license' and stays like that for ages (left it going for 2 hours once)- so can you just go through your sequence of what you did
Same as you by the sound of it.
I just kept switching the proxys.
Before the re-install of XP I got various messages, including the "insert DVD", "out of region" and "using anonymous proxy", plus the message you mentioned.
When installing XP I activated, but didn't register Windows, and I used DVD Region Killer, along with Proxy Switcher, even though my drive is multi region.
Another thing is I'm now using Media Player 9. I think this makes a difference too. Sorry I can't be more specific, but I tried so many ways to activate it.
I don't think you're missing much anyway!
