Here is the info from the Installer Log (sorry if this is a pain to look at - I'm not sure the best way to display it besides just copy/pasting from the "errors and progress" log window). It looks like the first problem might be related to a "Can't inititiate distribution from ..." line about 1/3 of the way down. Unfortunately I don't really know what any of this means. Any thoughts? Thanks folks!
