Password Reset - An Error Has Occurred! Invalid activation code

[Jadzia]

Hi

On using the forgotten password link I am getting the above error after entering the new password.

I've seen a few posts on this but nothing in them that has fixed the problem.

Joomla 1.1.2
Orstio Bridge 1.1.7

I'm using Artio's SEO however with nocache for smf - if I have it disabled for smf it breaks the whole forum (all links lead to rome, aka site home page www.narromine.biz [nofollow])

Cheers anyone who can help!
