This is a follow-up to my previous message with additional information.

I have an urgent problem!  All of a sudden, when I opened MSExcel 2000, it
tried to open many, many files, one right after the other, without regard to
the file format.  It also kept giving a "format is not valid" message with
every document.  I am running Windows 2000 and Microsoft Office 2000 Small
Business (version 9.0.3822) on a Dell Dimension 8100 with lots of RAM and
lots of conventional memory.  This computer is not networked.  My firewall
is ZoneAlarm and I have Norton Antivirus.  MS Office 2000 was pre-installed
by Dell,  I have tried re-installing MSOffice 2000, but that did not fix the
problem.  I am unable to get into Excel to change any options, because every
time I open it, it just begins opening one file after another and does not
give me the opportunity to change settings.

When I ran Norton Utilities to try to fix the problem, I got the following
message:

"C:\WINNT\SYSTEM32\MAPISRVR.EXE" cannot access a necessary file "gapi32.dll"
"gapi32.dll" might be located on a removable drive, a non-visible volume
such as an NTFS drive, or on a network.  .you might need to reinstall
"C:\WINNT\SYSTEM32\MAPISRVR.EXE".

I can in fact locate "gapi32.dll" in the folder "C:\Program Files\Common
Files\System\Mapi\1033\NT", but I cannot find the file "MAPISRVR.EXE" on my
computer, so I guess it does need to be re-installed, but how can I do
that?.  I don't know whether this latter problem is related to my MSExcel
problem, but I must assume they are related since they seem to have occurred
at roughly the same time.

I am sending this message to several newsgroups, because I am not sure which
application(s) is the source of these problems.  I would appreciate any help
or advice anyone can offer.  Thank you.
