senuke XCR error

hey, i watched this video http://www.youtube.com/watch?v=hoeqSZYV-Lg about creating wordpress script in se nuke xcr. But i have problem, i created all steps but when i run script from step 1 im getting error : "The length can not be zero. Parameter name: OldValue". But when i switch to step 2 everything works, script fill all info - username password email etc. I tried with different sites and same thing. Maybe you know whats going on ? I tested it also on the newest version of senuke.
