Why example2 in file downloaded cannot be run?

I download dynarev4 and it can run example1 and ramst but cannot run exmaple2 because matlab is busy so long, so I guess it cannot run example2? Anybody have that experience yet? I want to know why?

I run Dynare v4 to do tlag2 and find it expense 24 minutes, I doubt v4 is really faster than v 3.065.
