Can anyone Help me why there is problem to generate timetable?

Please see this file. It is taking long to generate the timetable. What wrong is here?

Hello,

It is impossible. You want too much.

I attach liviub.fet, in which I deactivated many constraints, leaving for YS max 1 hours continuously. When generating, I stopped and saw the highest-stage timetable. FET cannot place this teacher's 14th activity, clearly.

Please make your data easier.
