I am new to the site and I am having trouble with the Install and Play function. In Internet Explorer and Chrome Nothing happens when I click on the Install and play. However with Firefox I get the error:
"The address wasn't understood
Firefox doesn't know how to open this address, because the protocol (maniaplanet) isn't associated with any program.
You might need to install other software to open this address"
How do I fix this? I am using the steam versions of TrackMania Canyon, TrackMania Stadium beta, and also TrackMania United.
