Yahoo Messenger - Client logs

Hello,

I have a question relating to Yahoo Messenger and the diagnostic logs it keeps. I need to find out more information about the logs in the

\program files\yahoo!\messenger\logs - folder. The logs in this folder contain information about the Yahoo messenger client and the connection with the central Yahoo servers.

For example, network_xxxx.log - where xxxx is the name of the windows profile account yahoo is running from, contains entries where the client is tryng to make connections to other yahoo users.

You can still chat and see the messages but was wondering how to interpret these log files.
I have a case that depends on this information. Any suggections as to where find the information would be greatly appreciated !!!

Thanks
