Access to old version?

Hi there,
I’m having problems with Staffer 2.1 and its modal screens. Basically when the modal screen pops up, the whole page becomes unusable with the modal blocking image covering over the whole screen.

I’ve used version 1.0 successfully before on other wordpress sites. Does anyone know where I could download version 1 from? I can’t see a link to previous versions on the staffer plugin page.

Thanks

Robert
