Hi Karen...
Whoahh! That's really heavy-I'm surprised that Adobe let's something like that into its product.
I have not had any experience with ATM, but I have had experience with OSs and corrupted system files. Is Windows functional - will it boot? If so, and if you installed ATM using Control Panel, use Control Panel to delete ATM. Then go into the Register, click Find, and do a search for all references to ATM, and delete them (make sure that the reference you delete is actually Adobe Type Manager-it should be pretty obvious). Then reinstall Windows right over the existing. Hopefully, it should reinstall the system files that were damaged. I have done this twice, and it worked for me. I can't quite remember if I booted to DOS and ran setup from there, or if I just used Control Panel, Install. I will check it out. Anyway, if you are going to hose the hadrdisk anyway, can it hurt, and maybe it will save you some pain.
