"An output module failed" error

I just installed CS2 AE and have been getting this error message on every attempt of rendering. After Effects error: Rendering error while writing to file"/users/...." An output module failed. The file may be damaged or corrupted/ (-1610153464)

I could render it as TIFF sequence but not in .mov or .mpeg. I could also render the same file in CS4 no problem.

Any solution?

Thanks,
aya
