I've lost the water shader [FX/ water (Simple)]

Hello There.

I was working with water, and I changed the script for it. Then i realized it was wrong, because the water Turned invisible. I pasted the original Script (I've copied it on wordpad before) on it, so the water could return normal. But it didn't, it became purple. I realized I pasted the wrong script, and now I lost the original one. I could be amazed if some of you could give me all the original Script.

THANKS! Also sorry for my poor English.
