The message comes from: src/init.c and relates to some start 
up handshaking between the TWs and the shim, as to downstream 
shim and upstream TWS server versions used.  IB makes some 
changes from time to time, amending these versions to permit 
them to add functions, and yet not break earlier third-party 
code releases, to some extent.

As I recall, we were working on this version checking (which 
is part of the initialization handshake) code rather intensely 
last week.  It is looking at the TWS version in this case.  I 
assume you are using something in the 862.X series, and we 
expressly moved to support the latest TWS in our efforts last 
week.

We have an unannounced version up which is almost certainly 
later than what you were testing with, and which should 
address 'stale version' messages at

Relevant NEWS ( http://www.trading-shim.org/capitals/?NEWS ) 
is:

date: Thu Oct 26 2006

 	* Port shim to tws 862.9, breaking, for now, backward compatability
 	        with the previous development platform, 855.5
 	* Fix intermittent but fatal handshake problem; please
 		consider upgrade

We anticipate formally announcing a slightly later pushed 
version, with some extensions on the order management function 
rolled in tomorrow.

inded it should work fine.

Thanks for the comment.  As I say, the version shim-061026.tgz 
has the fix you should need to permit running with the latest 
TWS.
