I just installed FieldsKit 2 and Twixtor 4.5.8 into After Effects CS3 on my new Mac Pro (Intel). Fields Kit worked fine, but Twixtor doesn't show up anywhere in the Effects Menu despite being installed in the plug-ins folder. Is there something I am doing wrong? Is it compatible with CS3?
Did you redownload the installer from our website? We've recently uploaded a new version that works with AE CS3 on Intel Macs, but we kept the same version number since everything else about the plugin is the same.
So perhaps you have a version of 4.5.8 that was before our recent upload? Can you download the latest version from our website (even though it has the same verison number), and see if that fixes your problem?
