First thing you should do is check your file versions. If the file was saved in a newer format it will not open on an older program. If this does not solve the problem, then perhaps it could be a hardware problem on your own system. If this is the case try opening the files in the same programs on another system.
Your first question is decided due to tool below. Second...I don't know
