Dear all
yesterday i encountered the following problem with my meseenger:
i found in the directory C:\Program Files\Yahoo!\Messenger\logs
some files in plus. I know that in this direcory must
be the following files:
billing_user
client_user
network_user
performance_build_0
reliablemessaging_user
voice_iuliana_0
ycp_user.

But here i found in plus :

billing_iuliana
client_iuliana
network_iuliana
performace_build_2162

When i opened this files, there weren't empty.I found some strage logs
here such as
"2009/01/19 18:37:41.906[THRD:3248] [CLT] Info - ********** Log Started **********
2009/01/19 18:38:11.375[THRD:3248] [CLT] Error - Unable to load address book cache. requesting full feed; pNode: 0.
2009/01/19 18:38:15.484[THRD:3248] [CLT] Error - MAPILogonEx failed"

etc.

What can this files be?

I also found in this directory some strage files with strage names , there
were many of this, wich i deleteded it.

Please help me to find an explanation.

This doesn't seem like it has anything to do with Windows Live Messenger, yet alone Messenger Plus! Live.

All files seem very normal.

It appears that you have updated Yahoo! Messenger at some point (judging from the file names "performance_build_0" and "performance_build_2162")

And with that update came a few more log files (eg: "client_iuliana"), that's all.

The example text of one of the logs you put in your post simply tells you that, at one point, Yahoo! Messenger tried to connect to your email ("MAPILogonEx failed") but failed for some reason, eg: bad connection.

Nothing out of the ordinary.

More detailed info can probably be found at one of the official Yahoo! Messenger-sites:
Yahoo! Messenger: Help
Yahoo! Messenger: Tutorials
Yahoo! Answers: Messenger
Yahoo! Groups: Messenger
etc...


Remember, this is a forum about Messenger Plus!, an addon for Windows Live Messenger, which is a completely different IM program.

Thanks  for your help.
