Error calling generated SFunction, AAF_03_sfun. Error calling MATLAB function 'AAF_03_sfun'.

I'm using MATLAB R2012b. And my model 'AAF_03.mdl' is a model of the MATLAB R2011b version. It contains stateflow chart. I don't see this message when I run a simulink model which doesn't contain any stateflow charts. How can I fix this problem?

Have you used

slupdate

to update the model?

I can't use slupdate. Same error message is coming out. But I have already updated the model to R2012b's model through 'Upgrade Advisor'.
