CTD stands for Crash To Desktop.
The Game just goes away and your back to the desktop.
There can be many causes for this.
Not just in game problems but outside game problems also.
Start by listing your operateing system (XP, Vista, Windows 7)
System specs (Ram, processor, etc)
What mods you use on top of SH3
What's running in the background (Virus programs, IM programs, etc)
The more details?
The better We can help.
