What happens when you try?

I'm gonna guess that you have two instances of excel open and you're trying to
copy|paste between instances.

Try closing one of the workbooks, then use the other instance of excel to do
File|Open.

Then try the copy|paste.

If this isn't close, you'll want to post more details.
