Happily you guys turned out to have downloadable separate files for exactly this case!

My windows install will not complete, I'm unable to fully download the .uqm .7 content, exact text of the dialog box showing failure is:

Could not install the package uqm-0.7.0-content.uqm due to the following error: "resolving hostname".  This is a mandatory package. Without this package the urquan masters 0.7.0 will not run. do you want to try from a different mirror?

So far no mirrors have worked.
