Vista - Windows Security Center doesn't recognize CA Anti Virus

Running Vista Home Premium
CA Anti Virus 8.4.0.24

The security center warns me that I have no anti virus when clearly I do
(see above)
The security center will NOT turn on Windows Defender even after I have told
it to and it scaned for updates.

WHY?

latest updates (both program and definitions?) It's been my
experience in the past that either can cause Vista to think it's
unprotected. CA should register with Vista just fine--as it's listed
on Vista's official security page.

No plus

Def's are up todate. i will try re-regestering again. I read that CA is one
of the few anti viruses that works with vista and is recommended by vista.
