Thanks for the offer, MarkL, but I got it through a proxy connection. If anyone else is having difficulties, he can try http://www.blowtorchscenarios.com.nyud.net:8090/ , it worked for me. (I still can't figure out why I can't get into the site normally though, but oh well.)
Great scenarios. Thanks to JasonC for creating and George Mc for hosting, and all the comments in this thread.
