Problems After Updating To V 12.0.12

I have Bitdefender Internet Security 2009 12.0.11 installed .When I upgraded to v 12.0.12 after rebooting the system tray icon has disappeared and the Antispam settings are greyed out and can't be used.

I then removed v 12.0.12 and reverted back to v 12.0.11 and everything works fine again.Has anybody else had this problem?

I now only download the definitions and not the program upgrade.

I run a Compaq Quad Core System with 4GB of Ram on Vista Home Premium .

Thank you
