Running DTS package in sql server 2008

When I tried to run the DTS legacy package in SSMS 2008, and I tried to open  a lookup, the screen freezes and I do not even get an error message. It just won't work and I have to kill the process.

The screen shots look like this:

The same error occurs when I select build query in the transformation source.

My system information and other details:

OS: Window Server 2008 Enterprise without Hyper-V Service Pack 2

SQL Server: SQL Server 2008

CPU: 32 bit

I have both of these installed:

 Microsoft SQL Server 2000 DTS Designer Components 
 Microsoft SQL Server 2005 Backward Compatibility Components

 It is still not working.

I also did the following:

Copy  SEMSFC.DLL, SQLGUI.DLL, and SQLSVC.DLL
from: %ProgramFiles(x86)%\Microsoft SQL Server\80\Tools\Binn folder
to: %ProgramFiles(x86)%\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE

Copy RLLs SEMSFC.RLL, SQLGUI.RLL, and SQLSVC.RLL
from %ProgramFiles(x86)%\Microsoft SQL Server\80\Tools\Binn\Resources\1033
to %ProgramFiles(x86)%\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\Resources\1033

Reboot

I would really appreciate it if I can be advised as to what to do next or what I was missing?

Thanks,

SMP

Do you have a lot of activex script in that package? Have you used DTS exchange or run a DTSxchange profie using the profiler?
