Updater stops/freezes
Copy your friends City of Heroes installation folder to a Flash Drive, external USB drive, DVD, or some other media.
Paste those files into your City of Heroes installation folder.
Delete the coh.checksum file and start the updater. It should rebuild the checksum file and then allow you into the game.
If you continue to have problems at that point, post a log from running CoH Helper as it will give information about your system and the CoH installation and settings.
Also, post a log from running HijackThis. This will show what else is going on on your computer while you are trying to play CoH.
If the game spit out 20 dollar bills people would complain that they weren't sequentially numbered. If they were sequentially numbered people would complain that they weren't random enough.
Black Pebble is my new hero.
To add to what Texas said.. have your friend enable File Sharing on his CoH directory and then you can easily pull the files over your network a lot faster (you said he was connected to the same router).
Upon reaching "Fixing Files: piggs/texWorldV2.piggs" the updater will reach about 11mbs/42mbs and just stop indefinitely. I'm simply trying to run the trial version and this is kind of discouraging.
I have a friend plugged into the same router who has the game running right now without a problem so its not a port issue, its got to be something with my PC in particular I suppose.
