Line Breaks

I am having problems with formatting of my testimonials, specifically ones that I have entered myself from a previous testimonials plugin.

If I copy and paste the testimonial and save I get a one line testimonial that runs through the side bar and off the page on the right hand side. I have worked hard to add a line break (
) by counting every 75th character but it still is not showing very well.

Do you have any ideas for me so I can use you plugin?? I really love it other than this formatting problem.
