PhP Forums @ my site

Hello Folks-- When I moved my former PhP BB from an old provider to the new one--- I was more than lucky--- I was able to backup the database and somehow-- get it imported and working and I only lost one message post by one user. When I log into the control panel of the Forums, it shows: Powered by phpBB 2.0 RC-3 © 2001 phpBB Group I am not a programmer or pHpBB expert by any means. With that said- how can I get the Forums upgraded to the current software release without losing my existing Messages/Users ? Any HELP is most appreciated ! Thank you, Matt Brunk the Group http://www.nbxgroup.com the Group is not affiliated, endorsed, or sponsored by 3Com Corporation of Santa Clara, CA.
