my programs don't run on the 2012b version anymore

I have recently upgraded to Mastlab 2012b, however several of my programs have now stopped working. programs using fminsearch seem particularly effected. do you know if i need to download some additional libraries?

I still have Matlab 2009b on my desktop which I'd like to use however this wont run because the license is presumably out of date, could this license be restored for previous versions

"have now stopped working" <= What does that mean exactly? Do you get any error?

the error messages are

Error in fminsearchcon (line 320) [xu,fval,exitflag,output] = fminsearch(@intrafun,x0u,options,params);
