Compatibilty between CB1.4 & Artio JoomSEF

Hi everyone, I made the upgrade of my CB from 1.3 to 1.4 on my joomla v1.5 today, following the txt file "README-UPGRADE.txt" step by step, but when i went to check if everything works fine i realized that the user registration process doesn't work: when i click "submit" appear a page that show "you are not authorized to view this page"!
I made some tests:
- I have create the mandatory menu link pointing to the User Profile item
- I have removed my CB completely (including MySQL tables) and made new clear installation
but the problem still remain until when i disabled Artio JoomSEF from admin panel!
I will go back to the cb v1.3 but hope you will check this problem!

CB is only compatible with default Joomla SEF, we do not test or support 3rd party SEF extensions. There's likely some sort of URL rewrite happening for the POST url of the registration form. When upgrading you should purge all your URL rewrites from your SEF extensions so it may re-create them as necessary. Please also check that your links to CB are published and public (the module they are on does not have to be!).
