How do I over come the path problem?
Contact your host and ask them for the full path to your web folder (the folder your home page resides in). Eg.
/mnt/web_a/d44/s99/a090abxa/web
Once you have your full root path, open up the _cfg.cgi and look for a variable named $DefaultData on around line 50.
Set this variable to your full root path. Eg.
$DefaultData = "/mnt/web_a/d44/s99/a090abxa/web";
Upload the _cfg.cgi script (overwrite if you have to) and re run the setup file again.
