Comments in configuration files are not usually a problem.
Perhaps the comments included unusual characters which confused Tunnelblick.
Could you edit a copy of the original configuration to remove the remove IP address, then compress that and post the .zip? (The .zip would preserve unusal characters in the comments and I could look into why Tunnelblick failed to deal with it properly.)
Control-click on the file and select "Compress..." to get a .zip of the file.
Thanks.
