[TxMt] Error using blogging bundle - MovableType

I'm using movabletype 3.33 when I post an entry I get an error posting it /usr/lib/ruby/1.8/xmlrpc/parser,rb:154:in 'fault':wrong fault- structure: {"faultCode"=>"server","faultString"=>"Can't call method "param" on an undefined value at /web/script/onegoodmove/ onegoodmove.org/mavabletype/plugins/commchallenge/lib/ commchallenge.pm line 48. \n} (RuntimeError)

I get a similar error when posting from del.ic.ious Can't call method "param" on an undefined value at /web/script/onegoodmove/ onegoodmove.org/movabletype/plugins/commchallenge/lib/ commchallenge.pm line 48.

Any help is appreciated.
