This is a user-to-user forum. We are just users like you and don't have access to the information you are looking for. What version of Lightroom do you have? How was it purchased? Is it a package, or is it a downloaded version? Do you subscribe to the creative cloud? What operating system are you using? If you provided a few answers to some questions we might be able to give you some assistance.
A soul mate have fixed for me. Lightroom 5 is working. HIP HIP HOERA!
