Errors in Quartus II 10.1

I just "upgraded" from Quartus II 9.0 to 10.1, and now I have two new errors which were never there before.

First, whenever I click the new project wizard, I get the error "Quartus II settings file contains an illegal device family -- using default device family Cyclone IV GX"

Second, when I click "View new Quartus II information" or "Documentation" or any other web based link, Quartus II crashes with the following error:

Does anyone have any ideas as to why I'm getting these errors?

Thanks!
