MTA:SA error code
MTA:SA error CD38
The server does not accept your version, and the message says which version it wants.
How to fix it
Install the current MTA update
Close MTA and run the current installer from multitheftauto.com. Several connection codes are simply an old client meeting a newer server.
Try the connection again
Close MTA, open it again and connect once more. A single failed attempt can come from a restart on the server or a short break in your own connection.
Still not fixed? Copy the whole message, not only the code, and check your log in the Fix tool. It is read on your own computer.
About this code
A CD code appears when a connection to a server fails, is refused, or ends. Most of them carry a second line with the server's own reason. MTA's own documentation gives CD38 as Unsupported version; details.
