Failed to import an unmanaged solution to CRM organization

I got an error when i import an unmanaged solution from Dev to Test

The solution has account, contact, lead , opportunity, case  and user entity and also a javascript web resource.

This is the error:

You are attempting to update in the active context when there exists an active row, but either the active row has a state other than publish or unpublish or you are attempting to do a published update of a publishable component, which is not allowed.  _Input.IsBeingPublished: False; CurrentState: Microsoft.Crm.Platform.SolutionAwareComponents.BusinessComponentState

I got a clue from the link: http://social.microsoft.com/Forums/en-US/83f66edd-0ec3-45f0-bc82-b63122d1ff7f/failed-to-import-managed-solution-to-crm-online-trail-version?forum=crm

I tried this link but unsuccessful.

It will be great if anyone can help.
