Topic — Incomplete network profile.
LAN Bridger cannot join the requested network because the network profile you provided was incomplete. Contact the administrator of the network to obtain an updated copy of the profile, and then try joining the network again.
Details
Network profiles are XML documents that must conform to a certain structure in order for LAN Bridger to make use of them. This profile does not conform to that structure, likely because a tag is missing, an attribute is missing, or a chunk of the profile simply does not exist.
Typically this happens when the way in which you were given the profile somehow failed. Perhaps an e-mail was cut short or an instant messaging file transfer failed.
Asking the network host for a new copy of the profile is the best way to handle this situation. If you are the network host, you should consider creating your network again.
