Hot on the heels of GridIron releasing Nucleo Pro 1.0.4 today comes word that this update will NOT work with the After Effects 7.0.1 update. The word from GridIron is:

We are actively pursuing a fix for this problem and will have a new release ready as soon as possible.

So if you jumped out there and installed Nucleo Pro 1.0.4, GridIron recommends backing off to the 1.0.3 version if you are running AE 7.0.1. If you haven't updated AE yet then your good to go with the new Nucleo Pro version. I received this info via an email alert and they don't seem to have any info about this on their website yet. I'll update this post with a link as soon/if they post more info. See, I told you updates were scary.

UPDATE: GridIron has quickly addressed the issue and the new update is available for download. The new build is version 1.0.4 Build 391. All systems should be a go now with the update and After Effects 7.0.1.
