Hi,
I think you are copying the wrong file. The file name you mentioned is a template for users databases, not the actual the user database. If you have version 10 or later, the location of the user database depends on your operating system.
Windows 2000/XP
C:\Documents and Settings\<USER NAME>\Application Data\National Instruments\Circuit Design Suite\<VERSION>\database\UsrComp_S_USER NAME>.usr
Windows Vista/7
C:\Users\<USER NAME>\AppData\Roaming\National Instruments\Circuit Design Suite\<VERSION>\database\UsrComp_S_USER NAME>.usr
If you cannot find it there, you can find the path in Multisim
- Click Options > Global Preferences
- Select the Paths tab
- Find the User Database row
