[support] Workflow "Unknown State" issue

-I have a workflow(2) with states A, B, and C, . - I had a workflow(1) that had states c, d, f which I deleted. - My content was initially in workflow(1), which I deleted. I used "*Workflow post install*" module to move content to the new workflow(2). - Some of the content moved into workflow(2) but some did not. - the ones that did not move into the workflow(2) have "unknown state" as their state.The state is only viewable when I generate a view(under field "workflow : Current State"). - there is no provision of editing the workflow,When I click on the workflow tab.

-the content that moved to workflow(2) and the ones that did not, all are of same content type.

my question is...how do I move this content into the workflow(2)?

please help
