Does anyone know if I run the boards through a new install, will it wipe out my boards and posts? I uploaded the config file in seversl different places and this is what I get when I go to the install.php page:

SQL Error: Unable to connect to database server, please try again in a few minutes.SQL Error: Unable to connect to database server, please try again in a few minutes.
Fatal error: Call to undefined function upgrade_header() in /home/mystuff/forums/install/upgrade.php on line 67


I uploaded the file in several different places, under forums, admin and install. Any suggestions? Thanks.
