Error updating local ID file

Dear all

My colleague is running her notes ID on XP PC… juz did a ID re-certification. I am not sure if he had accepted the certificate…

Three days later, he got this message:-

Error updating local ID file: Cannot access or create the ID file.

Why is that so? Is it something to do with re-certification? Can someone shed some light to this problem to enlighten a Notes newbie (me)?

Tks in advance.
