PDM Workgroup Update problem

We did the upgrade to SW09, and updated SW to SP4.0.  However, we cannot get the PDM Server to update from SP0.  Our VAR is struggling with trying to help.  When we go thru the process, it seems like our license is confirmed by Solidworks but the process seems to freeze.  Can someone give us the simple 1-2-3 steps?  Thanks.SolidworksWorkgroup Pdm
