Remmina can't remote into Windows Server

I'm trying to use Remmina on Ubuntu to remote into one of the servers at my work. However, after entering the connection information in I get the following error: > You requested a H.264 GFX mode for the server user@server", but your libfreerdp does not support H.264. Please use a non-AVC colour depth setting. I am quite new to Ubuntu in general, so I am not really sure what to do about the above error. Could anybody help me out?
