Put # in front of the triplew, bronze, downloadg (and silver, if it's there in your hosts file); also make sure you either don't have a carriage return after the very last non-# entry in your /etc/hosts file...or alternately, make sure the very last line in the file starts with a #.
Example /etc/hosts file (partial-includes just the Garmin stuff):
127.0.0.1
Code:
http://www.garmin.com
127.0.0.1 gold.garmin.com (if this is the very last line in your /etc/hosts file, make sure you do not hit the Enter key or otherwise insert a Carriage return at the end of this line)
or
127.0.0.1
Code:
http://www.garmin.com
127.0.0.1 gold.garmin.com
#127.0.0.1 downloadg.garmin.com
#127.0.0.1 triplew.garmin.com
#127.0.0.1 bronze.garmin.com
#127.0.0.1 silver.garmin.com
# (this is the
very last line in the /etc/hosts file--do not hit the Enter key after typing this line)
Also make sure you have the right settings in the required plist files (see elsewhere in this thread for which plist files need to be modified).
