Solution: Delete those files.
Are they corrupted? After a recent virus attack, I've noticed some programs have problem loading due to certain files under My Documents folder. I am not sure if the files are corrupted. I ended up having to delete those files pertaining to the programs. And then the programs loaded fine, creating new My Documents files.
I wonder why wouldn't the files be overwritten. Perhaps it's using the principle of "if file exist...use current (corrupted) file."
I should open one of these "corrupted" files in someway and see how "corrupted" they really are.
Thus far, problem programs are e-sword, opened fine but with blank error dialog boxes until problem fixed by removing the private study notes files under My Documents. The other program is Readiris, scanning completed but error: Internal DRS error: 1800:c0:120" etc. couldn't save to document file. Removed pertaining file under My Documents, including previously saved scanned file, problem solved.
Some virus.
