[Rails] dispatch.cgi not found error

[Eric Ocean]

I'm following along on the 10 minute tutorial. Accessing blog at 
http://www.ampede.com/blog/ works fine. I then created Weblog using the 
script/new_controller generator. When I try to access 
http://www.ampede.com/blog/weblog/, I get:

-------------------------------------------------------------
Not Found

The requested URL /dispatch.cgi was not found on this server.
-------------------------------------------------------------

I'm being hosted at textdrive.com if that helps, and I'm using their 
Rails setup.

P.s. Is there somewhere I should be looking for answers to these kinds 
of questions. I found the Wiki difficult to find stuff with.
