kmeans not working in MATLAB 2015a

I have MATLAB R2011a and was thinking about updating to 2015a so I got a trial version with all the toolboxes that I need for evaluation.

For some reason MATLAB 2015a is unable to do the kmeans function I always keep getting the same error

The class "internal.stats" is undefined. Perhaps Java is not running.

Error in kmeans (line 136) [eid,errmsg,distance,start,reps,emptyact,online,options,maxit,display] ...

needless to say the function works just fine on the old MATLAB which is still installed on the same PC so I don't think is a java problem. Anyone knows why I am getting this error?
