We just updated ReelSmart Motion Blur to version 3.2.4. What's new:
Fixed a problem where RSMB 3.x and RSMB Pro 3.x plugins may not produce frame, may inappropriately stop a render, or even crash within After Effects 7.0 when the layer had AE's Time Remapping, Time Stretch, Time-Reverse Layer or Freeze Frame applied.
Fixed a problem where a red frame might flash when interactively scrubbing along the timeline within AE 7.0.
The update is free to previous licensees of version 3 of ReelSmart Motion Blur.
