Cloth simulation problem.

So I made a cloth for a scene in a series of architectural renders. I had the cloth animated but I went into edit mode to UV unwrap it to apply a texture and now the cloth simulation wont animate. Please help!

Go to frame 1 and hit alt-a.

Better yet, go into the physics setting, cloth cache. Set the start and end frames and hit bake, and you should be good to go.

thanks even though I tried that before it started working again after doing it multiple times lol go figure.
