toXPcTarget block broken in xpcTarget 2.7 (SP2) ?

Hi,

our department recently installed SP2 for Matlab R14. However, after
this update all xPCTarget applications that include a ToxPCTarget-block
stopped working. On the Mathworks homepage it said that the RTW-Settings
need to be correct (xpctarget.tlc and correct target destination), but
this was checked by us.
The error message we get says "Error when initialising block ... Cannot
find property SystemTargetFile". And truely the block in question does
not have this property as to my knowledge it is a property of the parent
simulink system.

Has anyone have similar problems? Any hints?
