Failed to Open document

I am recieving the Failed to Open Document error when I try to open my files in mx2004. I know people are very quick to blame this on the crack but I am using one of the lab computers at my school and I know it isn’t a cracked version.

Any ways, if someone could tell me what is up withthat I would be forever greatful.

check to see if the files are corrupted. either that or the file is protected.
