hello. PLEASE! I need somebodies help!!
before i downloaded Messenger Plus!, i had the normal MSN, the newest version... and i was constantly chatting with one contact, and when i went into my history folder, and wanted to see the chat, i get the folowing error:


The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.


--------------------------------------------------------------------------------

XML document must have a top level element. Error processing resource 'file:///C:/Documents and Settings/Owner/My Documents...



and after i download Messenger Plus! and i go to the features > chat log viewer
i see the folder, but it's empty though i chatted with the person last night.
is this happening in the Messenger Plus chat log viewer because i didn't fix the error? if so, can somebody please tell me how to fix this.
and if not, please tell me what the problem is and how to fix it.
your help would be very much appreciated, Thank you!

P.S. This is only happening with one contact. All the rest are fine.
