I'm using Acid Pro 7, which I downloaded yesterday. I've run the program several times already. At some point, when I incorporated some VSTs into the program, it hanged. I had to force End Task, after which I restarted. Since then, whenever I try to launch, the program hangs. As it is loading up, an error message appears (something like: No iplib.dll found in waterfall). It continues for a while, then stops when it gets to playripl.dll. The program does not freeze--there is no "not responding message." It just stops.

Thank you for any help you can offer.
