I took my computer to the clinic, got it back yesterday and it worked ok for a while, but now I get an error message:

IE SCRIPT ERROR
A YELLOW TRIANGLE WITH AN EXCLAMATION MARK IN IT.
An error has occured in the script on this page
line 58
Char: 9
error 'top.date Format' is null or not an object.
code 0
url MHTML:mid://000000 14/

Do you want to continue running scripts on this page?

YES   NO


Should I take it back, or can someone explain this?
