The best suggestion I can find is to do a complete wipe and reinstall everything. I just want to reinstall it over the old server, because some of the files became corrupt. I tried to delete the Server app with App Cleaner which deleted a bunch of files with it, but when I try to reinstall the Server app it just loads, ask me to pick a computer/server to work with, and then just hangs. Its worse than before because now I can't even get into the app properly, and just wish to reinstall over that app. Thanks for any help!
