SEVIS Terminated.......Applied for H1B......Got RFE....Reinstatement

When I applied for H1B, I did not submit client letter.Now I got RFE to provide a client letter. But now I have changed client and client location.Can you please advice me that what I can do in respond to RFE? another question is that my university has terminated my SEVIS because I did not maintain my F1 status…And now they are saying that you have to apply for reinstatement.I have already registered courses in summer classes. Becuase in Spring semester, I did not maintain my F1 valid status. What should I have to do ? Does it impact on H1B approval? How lond it will take to activate SEVIS ? Is there any other option that If I will pay new SEVIS fees to generate new SEVIS? Thank You.
