Since I installed the Office 2004 for Mac 11.6.1 Update, a few days ago, I cannot open three files. It seems that all other excel files will open without issue. I can view the contents of these three using the OSX (10.5.8) viewer with no issues.

There does not appear to be a problem with the files as they open with no problem on another computer, but when resaved with a new filename they again fail on the primary computer.

I have reinstalled the Office 2004 for Mac 11.6.1 Update and checked the previous update as well 11.6.0; all appears to be ok.

Restart/ shutdown do not have any effect.

I am stumped and i really need to keep using the files. Any suggestions are welcome. Next step is open office, but i'd like to keep using the MS Office.

Thx for your help.

most here don't use a Mac ,thinking you might get more help on a MAC forum .good luck
