Forgive me if I'm wrong, but with the pen tool, I believe you don't need to hold down alt for it to be curved. You can also use the direct selection tool(white arrow) to find a "handle" on the line, which allows for curving also. It may depend on which version you use, I use CS5. Also, pretty dumb, but make sure you dind't click the "add anchor point" under the pen tool's drop down... that could be a problem.
