I get the error Failed to connect to the server
We have records of you using a different username.
At this time we don't allow those with a changed name to connect.

I get that this is the server policy and I have not played on the server in a very long time but
I never actually changed my name.  I think it's the fact that my in game Name use to be Djinn42
before Mojang had the switch over a while ago and after the fact it was changed into djinn42

How can I get this fixed so I can play on the server again?  If I don't hear back I guess I will
try to switch my name back to Djinn42 instead of the lowercase djinn42.

If anyone else has positive suggestions please let me know.
Thank you
