Having problem with templates

I'm using Firefox 3.6.6 and have been since I first started using ServiceDesk. I just recently upgraded from our outdated 7.5 build to the latest that I found on the website of 7.6.0 build 7608. When I try to enter a new request, everything appears to work until I get to the "Add Request" button at the bottom of the page. "Reset" works, and "Cancel" works, but "Add Request" just depresses and then returns to normal. The only way I have of entering requests is via email. I have also tried Internet Explorer 8.0 and Google Chrome 5.0.375.99 beta and neither of them work either.

I discovered also, that any template that was created over a year ago (before I took over) seems to work. Any template that I've created since then does not work. Anybody having similar issues or have had similar issues?
