Good day,

I'm having a difficulty opening a .xls file using a Ms Exel 2003.

It prompt a box saying:

The file you are trying to open, 'AA.xls' is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you wan to open the file now?

If i click Yes. Another pop up will show:

The information you were working on might be lost. Ms. Office excel can try to recover it for you and i checked on the " recover my work and restart Ms.office excel"

A blank Ms.Excel will be shown.

The size of the file shown on the icon are still there but nothing contain in it.

Pls. help.
