Fatal error after unsuccesful upgrade

What was the error of unsuccesful upgrade?
You can disable AceSEF via FTP:

OPEN

administrator/components/com_acesef/configuration.php

FIND

var $mode = '1';

REPLACE

var $mode = '0';

At this point I would suggest:

1. Export your URLs
2. Uninstall AceSEF
3. Install AceSEF
4. Import URLs into Backup / Restore page

But i cannot export urls, since acesef when i try to use the control panel or any options, it still gives me the same (above) error!!!
