Matlab's profiler does not show anything

Hi, I'm trying optimize a program, yet for some reasons when the program stops, the profiler pops up yet it shows nothing (in the image). I don't know why it behaves that way. Please help me, thank you very much :)

@Dang Manh Truong: how are you calling the profiler? How do you call the code that you want to profile? Does the code consist script/s or function/s?

What appears, if you pull the horizontal scrollbar to the left?
