Ah, I did not select Browser Download. I assumed the "Download Now" button was the browser download. I'm downloading SP1 now, so hopefully it will work properly now when I run fluid sims.
So, why make the working version (SP1) available as an optional download and leave the messed up version as the default? Seems like if the messed up version was simply removed, it would have never created the problem in the first place. I hope you plan on making SP1 the default for Sim CFD from now on. No reason to keep the buggy version online.
Anyways, thanks for your help! I do appreciate your prompt replies.
