Done Forum Name Change

I took a break from the network and in the meantime I changed my minecraft username, so I'm wondering if I could change my forum username too... I tried using the Update Username but it gives me this error: "It is not possible to change your username at this time. Please contact an administrator. (User does not have a UUID set.)", I want my name to be changed to "Terrails" (UUID: cc7d7824-a713-493b-8981-b7098d2aaaef)

 

bump

 

this is what I see when I press update username.

 

Thanks, I got notified in game to I have an alert so looks like everything is working
