Text background is a pink color. How do I get rid of it?

Hi everyone,

I had a computer crashed and have re installed Indesign CS3 after Adobe helped me by uninstalling the one for the died computer.

I installed it on a diferent computer but the text has a pink background in all my documents. Will this pink background print when

I send my formated books to my professional printer or in an e-book? How can I remove this pink background?

Thank you

Jan
