Can you tell us the exact error message you're getting? Do you have Internet Explorer 7 currently? From what I've read after a quick google of the problem, upgrading to Internet Explorer 8 has helped some people. Use the below link and click 'Download' to start downloading and then follow the installation instructions on the next page.

I don't know whether this will solve your problem, but it's a good thing to try until we can think of something else. If you can give us the exact error message you get when trying to copy and paste I can have another hunt for a solution.
