All my workflow rules are get lost and don't work

Hello Team

I have reported this issue to you on January 25, 2015. But still, I have not got any reply from you.

The request ID is 6246410. 

Even I made the screencast and sent it to you to show the situation.

Please help solve this issue as soon as possible.

I am very disappointed
