Trial SEF Adv 2008 Configuration menu in Admin auto closes it

[zoro]

Trial SEF Adv 2008 Configuration menu in Admin automatically closes it after openning for a split of a second, hence I cannot trial it on Joomla 1.5.3. All other menus (Alias & Meta, Redirect, etc) can stay open for edit but give error 404 when saving. I have tried to uninstall & reinstall it without success.

It was downloaded today and might be corrupted or not the full version of 1.2.5 for 5 day trial, and I am not allowed to try downloading again.

Strange. Has anyone else experienced this?
Please send your URL on mail so I can unlock it and you can download a new trial.
