Fatal error: Call to undefined function user_relationships_load() in /home/username/public_html/includes/common.inc(1696) : eval

Hi

Please help, urgent, i got this error on the entire site: Fatal error: Call to undefined function user_relationships_load() in /home/username/public_html/includes/common.inc(1696) : eval()'d code on line 1

meaning the site is broken. i got this after enabling a user relationship friend block on my side bar, i tried removing my theme but i just wont help. Tried removing UR and running db updates but that didnt help either, looked at the code. Im out of ideas.

Also: is there a way to delete a created block manually from the database, this could be my last resort.

Using 6.x.1.dev
