Registration redirection fails

Hi EasySocial 2.0 RC2

When a new user registers they should be redirected with automatic login to a predetermined page. This has been working fine but since upgrading to RC2 the destination url is missing a / so instead of going to http://mydomain.co.uk/index.php?etc it is being given mydomain.co.ukindex.php?etc so the process fails.

How can I fix this quickly please?

Thanks
