Instant Facebook Login extension no longer working since upgrade

My website was using CB1.9.1 and to login I had the 'Instant Facebook Login' 3rd party plugin installed. This was all working great. I then upgraded CB to 2.0.3 and it now doesn't work. I have since updated it to CB2.0.4 and it still doesn't work.
When I try to logout I get a white screen and the url is www.ultrarunningcommunity.com/component/comprofiler/logout

Can anyone help me please as I believe no-one can login to my site at the moment.

I appreciate that it may not be to do with the update.

If there is no fix, can I downgrade to 1.9.1 again?

Thanks

Turn on Joomla debug to maximum level and see if your white screen gives more info.

You would need to contact that instant facebook extension provider for support.

You cannot downgrade from Cb 2.0 to CB 1.9.1.
If you have a backup taken prior to your CB 2.0 upgrade you can use it to restore your site.

I am now getting this message

Error: CB Login module not created (required).

I didn't get this before, so I'm not sure why I'm getting it now.

Can anyone shed some light on this please as no-one can sign into my site now and I really don't know what to do! I have posted on three forums now (Instant facebook login forum, Acymailer forum and this one)and no-one seems to be able to help.
Thanks,
Neil

This specific message means that you do not have a CB Login Module on your website.

Create on from the Joomla Module Manager -> New -> Community Builder Login from the list.
Configure and publish it.

I cannot help you with the other third-party module - you need to have that specific developer / support site help you.

Why am i getting this now and not before? Is it the upgrade?
Does this mean I have to use the cb login and can not use any third party module?
