Fast help please!

I've got Paint Shop Pro 9 and I have a quick question about something that needs to be fixed...like now, cause I can't make anything! So if anyone can help, please do.

Okay, so I open PSP and I go to make something. Once I hit the eraser, I can't see the settings you can make it at the top. Normally once you hit the eraser button, the size, shape, opacity, etc comes up on the toolbar but that's the problem...it's not. So I'm stuck with my eraser very large and very low opacity, which is hard to make walls with! It's the same with the freehand selection tool and paint brush too. And I'm going mad with not being able to change anything.

So PLEASE PLEASE PLEASE anyone, help me! :)
