M94A IRB6400 positions not ok

Simotion

I have reinstalled the  robotware on a S4 M94A.
Afterwards  I loaded system parameters and program from files I received from customer.
Now I seed that the positions are not ok : they do not  correspond to the positions from before the reinstall of the robotware.
And when i jog the robot lineairly along one axis (with reference base and tool0) the movement of tool 0 is not strictly lineair, and is also rotated.
Furthermore when I measure the position of tool 0 (in reference to the base of the robot) and compare it to the values in the jog screen (for tool 0 and base) it is more then 200 mm wrong at least.
One possibility is that the custommer had not the last configuration files (system parameters with callibration values).
Another thing I am doubting about, what if I have selected the wrong robot type during installation of the robotware?
Someone told me that it does not influence the position values, and if selected wrong, I would almost immediately get fault messages like current alarms from the motors.
Is there someway to check in an already installed system that the right manipulator was chosen during installation of robotware?
