Outlook 2000 Problems Again

I keep getting the error:
“The procedure entry point strtokex could not be located in the dynamic link library msoert2.dll” and Outlook hangs on receiving the 1st message. I have searched with google and searched M$ to no avail.
I have:
1. Deleted the outcmd.dat
2. Repaired Office 2000
3. Re-installed Office 2000
4. Re-installed Internet Explorer 6.0
5. Windows Updated
Any more ideas, or should I just uninstall this miserable program and use something else?
