I am using Steempipe's excellent EMBM water shader and it looks wonderful. Two questions/problems though:

1) The code for the water flow (moving the u and v coords) doesn't seem to do anything when I run. The water sits perfectly still. I've tried tweaking values and everything I can think of, but still no movement.

2) My team is submitting our Alpha tomorrow and the test machine will not render the water whatsoever. The water works on the laptops of all my team, but not on the test machine. We just downloaded the newest drivers possible yesterday from ATI. The computer is an Athlon 2600 with 512 MB ram. We are at a standstill trying to figure out whether to abandon the water or not, so any help offered is greatly appreciated.
