Hi Peter,
sounds like some sort of version mixing.
As you are running wM 9.10, you should use MFT/MAT 9.10 as well.
The mentioned Fixes should be superceeded by the IS_9.10_Core Fix, which also contains the CL part.
In general the Common Libraries as well as the Shared commponents group (SCG) should be applied to every installation participating in your landscape. This includes local Designer installation as well as every sperate installation like IS, Messaging, MWS, … for the case they are not installed in one single installation.
Regards,
Holger
