>Ok, I when back at the install CD and install an additional component. So, now, Full-Text search is now installed and running as a service. However, when using Enterprise Manager, I still can't have the option enabled when I select any database. The help says to select a database and click on that option from the menu. However, the option never comes enable.

Ok, don't worry. This one was cause by the fact that SP3 was enabled so I had to re-run it again in order to have the Microsoft Search service to react.
