[Solved] Error - please tell Martin, ID=204

Hello,

i have installed SEF Advance Trial.
If I activate this component the startpage of my site is empty. Only the following text was shown: Error - please tell Martin, ID=204  ???

Any idea who the problem is?

Kind regards,

Roland

Edit: Problem solved...

I guess Martin solved it?

I have delete the sef_ext.php from remository... Now SEF advance work but not the SEF-Urls for remository...
