I have an existing ACT! 2006 database that is only allowing 4 active users. The client has given me their email from back in November 2005 showing a list of 10 serial numbers that they purchased. How do I apply these additional licenses to the database? I tried the 'Help'/'Register ACT...' menu option, but it only allows one serial to be entered and those end up at 4 max again. Suggestions? Thanks in advance.
