Hi, I am still having these issues... Although now the full interface for Color Finesse 3 does load, it is however giving me a pink grid and stating I am in a trial mode. When I click about in the effect panel it shows that it is registered to me, I filled in the registration pop up box a couple of days ago.
Perhaps a version of Color Finesse PI was installed in trial mode which would cause the pink lines. To eliminate this, download the latest Color Finesse installer from our website, and when asked, specify that you want to install the "LE" version. This will eliminate the lines if this is the issue.
For the problems launching the Color Finesse UI, be sure your memory settings in After Effects are leaving sufficient memory for other apps. The Color Finesse UI is one of those "other apps" and has to have enough memory available to launch and run.
And by "our website" I meant synthetic aperture "dot" com.
