MTA:SA launcher code
MTA:SA error CL04
MTA could not restart itself to finish what it was doing.
How to fix it
Close everything and start MTA again
Make sure no MTA or GTA process is left running, then open MTA yourself.
Repair your MTA installation
Run the current installer from multitheftauto.com over your existing installation. It replaces MTA's own files without touching your settings.
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
CL codes come from MTA's launcher, before the game starts: installing an update, finding GTA, loading MTA's own files or starting gta_sa.exe. MTA's own documentation gives CL04 as Restart failure.
