Hi, I'm also getting the same error. My scenario is, I'm trying to write a simple approval workflow that uses an Infopath form for edit form. Workflow is started. when I click the title filed in the task session of the work flow. I'm getting this error "The following location is not accessible, because it is in a different site collection:"Infopath form URN" " . where the infopath form is supposed to showup.
