You need to set your database type in your config.asp file like there error says.
Open your config.asp file and uncomment one of these lines (probably the Access one):
'#################################################################################
'## SELECT YOUR DATABASE TYPE AND CONNECTION TYPE (access, sqlserver or mysql)
'#################################################################################
'strDBType = "sqlserver"
'strDBType = "access"
'strDBType = "mysql"
to uncomment you need to delete the ' that is in front of the line you want to use.
