Hello Mx_Jan
Sorry to take so long getting back to you - ill health is a
restriction
The fact that the message refers to an invalid argument or
procedure ponts to a macro failing. These are normally part of an
add-in. Were there any add-ins in the list (not templates)? If so,
uncheck each in turn until you find the offender.
Also check what Office updates were applied just before the
problem occurred. unistall the updates at that point; you can
always update again later. another option is to restore your system
to a checkpoint prior to the problem occurring.
Let us know how you get on.
Regards,
Brian
