Ok I downloaded "Red Epic Importer" for AE CS 5.5 (10.0.2.4) running on a HP Z800 with 22 gig of ram.
1) I followed the 'Read me" file for AE of course I backed up 'ImporterRED.prm" and "ImporterREDServer.exe"
2) And I loaded the new After effects cs 5.5 Red preview files
3) When I re-start AE I get:
'After effects warning: The following plugins have failed to load.
Please reinstall these plugins:
C:\program files\adobe\abobe aftereffects cs5\support files/(media core plug-ins\common\importer Red.prm"
3) I double checked and yes I only have one copy of each file.
You are using After Effects 10.0.2.4? That is After Effects CS5, not After Effects CS5.5.
The RED Epic importer is for After Effects CS5.5. It will not work with After Effects CS5.
