server glitch?

[Thorgon999]

I was riding on my horse with diamond armor down north road, then the server glitched, said I can't fly on this server and disconnected me.  I was not flying.  When I logged back on, I tried to get back on my horse, but it said "You can't do that here."  So, now I am staring at my horse with the saddle and diamond armor it took me a long time to find, and can't do anything about it.  I'm at 210.76, 69.5, -136.781 on the north road.  Can anyone help me get my horse back?
