Error for After Effects - AEGP Plugin PNGIO Support

[revivee1]

Hi,

I am receiving the following error message in AfterEffects CS5.5 while attempting to render a project that I'd purchased from Videohive. In addition, I'm not sure what IDAT actually means??   I'm new to After Effects; therefore, any help would be very much appreciated.

IDAT are the data tables in the PNG file. That being case, the thing to do is to open your PNGs in a graphics program and save them from there in a format that can be used in AE/ repair damged PNGs.
