ProfileURL for JomSocial doesn't commit change, just redirects to homepage

Hello,

I've recently installed profileURL and am having difficulty getting it to work right. My system info:

ProfileURL 3.1.2
Joomla 3.3.6
PHP 5.3.13

Duplication:
changes HTACCESS
turned on SEF URLs in Joomla
Installed component
installed plugin / activated/ ordered to top
set to core - click on update link / redirected to homepage
created menu item for profileURL
accessed menu item / updated URL / clicked confirm / redirects to homepage / changes don't commit.

any help is appreciated =)
