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.
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.
