Just a quick observation: Some users experience trouble if CC3 is installed in the Program Files directory under Vista. CC3 likes to modify its own folder, but Vista does not permit programs to do that. The results of installing CC3 in its default location can therefore be unpredictable. I know it's a hassle to reinstall the program, but if you used the default install path, it might be worth it.

I am only an extremely casual user of CC3, though, and I've never experienced any of the Vista issues that some people report, so take my advice with a grain of salt.
