Yahoo SiteBuilder 2.1 flawed-need 2.0

I'm new here. 'ppreciate any help I can get. I mindlessly downloaded the 2.1 upgrade to Yahoo sitebuilder 2.0 and it blows. It's mangling code so that tables and "product modules" (little bits of code that pull product data from a data base), so that nothing displays as you save it. In fact, saves simply don't work!!! Yahoo support is useless. They absolutely refuse to find a way to simply get me a copy of 2.0, which though primitive, worked relatively well. Talking to the morons there is just like talking to a wall. Does anyone have a copy of 2.0 they could email or send me on a CD-I'll cover postage, shipping whatever. I have to get on with my business.

thanks
Peter
