Accidentally removed 'echo' from modplug, how do I get it back?

I accidentally removed the echo effect from ModPlug's effects list thinking I was just removing it from the current module because I decided I didn't want it in that module, but what I did was remove it from ModPlug COMPLETELY! how do I readd the echo effect back into ModPlug?
