problem packaging usmt 3.01 for SCCM 2007

Hi, all.

I have a problem during OSD task sequence.c The procedure stops during 'restore user state' with the following error in the reports:
----------------------------------------------------------------------
The task sequence execution engine failed executing the action (Restore User Files and Settings) in the group (Restore User Files and Settings) with the error code 2147942402 Action output: 0, HRESULT=80070002 (e:\nts_sms_fre\sms\client\osdeployment\osdusmt\userstateaction.cpp,95) VerifyIfPreLonghornBinary(sUsmtBinary, m_bUSMTPreLonghorn), HRESULT=80070002 (e:\nts_sms_fre\sms\client\osdeployment\osdusmt\userstateaction.cpp,523) SetUSMTBinary(), HRESULT=80070002 (e:\nts_sms_fre\sms\client\osdeployment\osdusmt\userstateaction.cpp,955) usmAction.Init(::GetCommandLineW()), HRESULT=80070002 (e:\nts_sms_fre\sms\client\osdeployment\osdusmt\main.cpp,235) Invoking ReleaseSource on USMTPackagePath C:\_SMSTaskSequence\Packages\FNM0000F Entering ReleaseSource() for C:\_SMSTaskSequence\Packages\FNM0000F reference count 1 for the source C:\_SMSTaskSequence\Packages\FNM0000F before releasing Delete source directory C:\_SMSTaskSequence\Packages\FNM0000F Released the resolved source C:\_SMSTaskSequence\Packages\FNM0000F OSDMigrateUserState finished: 0x80070002 IsUsmtPreLonghorn failed (0x80070002).

----------------------------------------------------------------------

i package usmt in the following way:
-installed usmt 3.01 on local sccm server on c:\usmt.
-copied InstallUSMT301_x86.msi into c:\usmt
-create usmt 3.01 package pointing to c:\usmt.
-replicated the package on the distribution points.

do i miss something?

Thx
