Root Messed up root

Ah! Using the AAHK (from here) I rooted my HTC Inspire. Everything looked good, but now when it tries to boot it gets to the HTC start up screen and blacks out.

I have no idea what I'm doing, but here's what I think is happening: AAHK erased the stock android, failed to install a complete replacement, and now all that works is the HBoot menu.

Is there a way to install a ROM using the HBoot menu? Can I do something where I put a ROM on the SD card and click "recover"??? If so, where should I put the ROM on the SD card?

THANK YOU SO MUCH!!!! Any help is hugely appreciated!
