I don't know what version you're using but the error is regarding the fact that the program can't open the file because it's to old or a newer version unsupported.
Try downloading the latest version: HERE
open the file you're having problems with and save the file type to the version you're using. v8 or v7 I presume ?
If all else fails, you could always give inDesign a bash. They also have a version you can trial for a few days.
