Instant rails 1.6, Win98, cookbook app fails

Hi all, have just started dabbling with instant rails over the last couple of nights, and first had some success running the typo and cookbook apps, with version 1.5. Upgraded to version 1.6 and an now getting a redirect error when trying to access the cookbook app. Tried both the development and production environments and am getting the same redirect error.

Any clues? Am I wasting my time trying to run this on Win98?
