Error Copying Reusable Workflows to other sites in Sharepoint 2010

Sharepoint 2010 has introduced new reusable workflows. When trying to copy and modify these resuable workflows, you may receive errors.

Use Sharepoint Designer 2010 to navigate to the subsite of your choice. Note: if you do not see any reusable workflows, you must create a blank one. This will create a location for you to be used for coping resuable workflows.

Solution: Expand "all file", locate workflows and copy your custom resuable workflow.

Lastly, select WorkFlows, then select your newly created reuseable workflow. In the "Forms" section, delete the forms. Next, save the workflow and select "Publish". This will recreate new forms and publish the workflow.
