Yes, that definately looks like the issue.
The 1st call to the MSN service works and a response is returned...the 2nd msg sent is the one i posted above. The MSN service simply does not reply to this...it should reply a NEW_VER msg or something if it worked as you would expect rather than not returning anything.

Hmmm...looks like I may have to revisit this app and write a new .NET version that uses the latest MSNP18 protocol.

Unhappy this project no longer works. I'll edit the main post.

Cheers,

Woka
