I just did a fresh install of Win7 64 and added the newest Emby Server and Emby for WMC. I had a working version on the old PC.
Now when I open Emby server dashboard it looks like I'm only setup as a regular user. I can view and search for titles...but there is no admin button or way to configure the program. How to I change my account status to be an Admin?
By chance are you running out of free space, or maybe transcode folder filling up? Will have to look but believe something like this happened with a free space issue.
