acces rights problem

[tim.goderis at gmail.com]

hello,

I've done something very stupid with my xwiki acces rights
on my wiki: http://timdropanalyzer.xwiki.com

Groups:
Access Levels: admin, edit, view, comment
Users:
Allow/Deny: deny
	
now i'cant modify my acces rights anymore, is there a way to reset them?

Greetingzzz,
Tim
