file not available

Microsoft Office Word

Word/Office will not let me open my saved documents. The 
document work when saved on a CD and used on another 
computer. The error message says File (then the file 
name) not available. Any tips. 

I tried deleting Office and reinstalling it. 
I tried clearing out old Norton Antivirus files.
If you're trying to open it directly from a CD, that's the problem. Copy it
to your HD, remove the Read-Only attribute, and then open it from there.
