I have just recovered from a serious AE fallover - took Adobe guys 3 days to sort me out and I think I reinstalled CS4PP about 7 times PHEW. but now I go back to a project full of plugs - all seem to have gone back OK except (so far) Stroke comes back with an error like "Stroke is not serialized - please re-install Stroke with the original installer" (probably not verbatim). Well what am I gonna do now? I'll bet the solution doesnt take 3 days! Actualy the Adobe guys tried really hard for me.
