Are you sure that the profile under which the services run are part of the correct groups? I had a problem with an upgrade to v9sr4 where although 'Local Services' is part of the local administartors group, the group was not explicitly defined in the 'Qlikview Administrators' group.
Hope this helps.
Could you please add some more detail to you issue?
What does the DS logs say?
Your best bet here would be to get in touch with QlikView Support and provide a detailed problem description as well as log files from the CC, DS, DSC and MS so that it can be treated as a semi-production down incident.
