I upgraded from Internet Security 2010 to 2011 specifically to get the Registry Cleaner. I successfully upgraded only to find the TuneUp tab MISSING! I sent a reply to Bitdefender's support email on how to update 2010 on Feb 1, 2011. Still no reply from Bitdefender Support. I've been bragging about Bitdefender to all my family and friends since I bought it. Don't let me down now! 
Any help would be appreciated.
