Last Saturday evening I was working with Excel and Word (both 2002 version) files.  All of a sudden, I could no longer open any files in either program.  After spending a few hours trying to determine the error, I restored the computer to the prior day's date.  This fixed the problem (temporarily).  Now it seems that about the same time every evening, the same thing happens.  Once I restore the computer to last Friday's date, Excel and Word work fine until the next evening.
