Purchased x plane 10 . Loaded all discs . Downloaded new installer as instructed. Trying to run, get the following error message.  upd socket read udp init failed. Message states the reason for error is because another copy of x plane is running. Have only one copy that has been loaded and will not let me in to do any  new updates or anything other than the new installer. Any help, please. Have sent email to x plane support requesting help but no reply yet.

Hello !

 

What's your operating system ? Did you try to restart your computer ?
