MTA:SA error code
MTA:SA error CD45
The client and the server fell out of step, and the message carries the details.
How to fix it
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.
Check your own connection
Open a web page on the same computer. If other things are also failing, fix the connection first. A working website does not prove a game server is reachable, but a broken one explains a lot.
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.
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 CD45 as Connection desynchronization; details.
