When I try to install Cog (GuillermoPolito.127) from the Configuration Browser in a clean Pharo 2.0 (Windows 7 x64), fails with the following message:

"The symbolic version #stable is not defined in ConfigurationOfCog for the current platform."

I download the image + vm with the following command:

$ wget -O- get.pharo.org/20+vm | bash

Any workaround?
