Ah-that must be it. Unfortunately I can't fiddle with the firewall, so
I will manually download everything.
By the way, after I downloaded the 300 MB
eclipse-modeling-ganymede-incubation-win32.zip folder, WinZip tells me:
"Cannot open file: it does not appear to be a valid archive.
If you downloaded this file, try downloading the file again."
Since it took an hour to download (This time the silly antivirus
software had to scan it as it downloaded), I don't think I will try it
again. Did I grab the wrong thing?
Thanks again for everything!
