[otrs] TicketHook Issue after upgrade to 2.0.1

Hi, I upgraded from 1.3 to 2.0.1, there were a couple of small database issues that I had to fix but all seemed fine. However the one thing I cannot fix is the TicketHook. Here is my setting in $OTRS_HOME/Kernel/Config.pm: Self->{'TicketHook'} = 'Call ID#: '; However all new tickets are generated with the subject [Ticket#1003147] instead of the desired [Call ID#: 1003147] I have of course bounced the webserver after making the changes to Config.pm. This was the setting I used in OTRS 1.3 Can someone point me at something I may be doing wrong ? thanks paul....
