Works in frontend, but can't access SEF backend

Hi

Needs help, after installing the latest SEF Advance 2008 i get this error when I am trying to access any menu in the SEF menu, in the administration.

Fatal error: Class mossefconfig: Cannot inherit from undefined class mosdbtable in /home/u/u4879299/www/administrator/components/com_sef/sef.class.php on line 0

www.polyamp.com

Joomla 1.5.9
JoomFish 2.0.1
SEF Advance 2008 v. 1.9.0

/Steve

I can't replicate this. Please send me a mail with the access info and I will take a look.

I think that I bought the wrong version, but Iam not sure I wanted the SEF Advance 2008 for www.polyamp.com

Can u correct my licence

Regards/Steve
