Adobe Live Cycle ES2 form question

Hello,

I am currently editing an Adobe Acrobat X form in Adobe Live Cycle ES2. I modified an existing e-mail address on a submit button already created. I saved the file, but when I either preview my changes in Live Cycle or Adobe Acrobat X Professional or Adobe Acrobat X reader, the old e-mail address appears. Has anyone run across this before? Could it be a compatibility issue.

Thanks for any assistance.
