>Maybe you have wrong version of the MS Office?

I have Office 2007. As for Word, maybe it is related to the fact that I had to remove the service pack of yesterday to avoid receiving the error I reported earlier on. I see there is another one being done right now. I will see if this fixes it. As for Excel, the document exists. However, I have to click on Unhide to see it. Many reported that this is normal. I haven't seen something on the net confirming a workaround for this.
