It is not likely that anyone will be calling you. You should explain the problem you are having with as much detail as possible, including error messages and actions you take before they arise.
This is primarily a user to user forum, although there are Adobe staff people who monitor and respond frequently. We do not call individuals who have inquiries. It is your responsibility to describe the problem in detail and then allow time for other users to respond. Besides describing the problem in detail, we need to know your operating system, the version of Lightroom you are using, the camera model you are using, any error messages that you are receiving, the amount of RAM installed in your computer.
