Open a command window from IR manager, cd into the cookbook directory, and then start mongrel manually. Make note of what ip address and port it starts on. I'm still working on the 1.3 release and starting mongrel manually brings it up on 3000. I think it starts on 3001 now (by default) through IR manager. At any rate, once it starts, open your browser using http://127.0.0.1:3000 (or whatever combination mongrel tells you it's using). Let us know what happens.
