Update and TrueCrypt problem

today my Comodo Firewall updated to this build. After restart I can’t mount any of my TrueCrypt encrypted volumes. It asks me for password which is not set (using keyfile instead). Ie. the old mounting credentials aren’t valid. I ask here because I didn’t change in system anything else than update CIS. Does CIS add any additional disk access monitoring that might block or alter access on low level? I see in menu new feature Viruscope. I don’t want anything like that 'coz Comodo Firewall self is slowly becoming a virus thanks to more and more file monitoring features like this. It should stay firewall and nothing more.
