Bloubul,
I think you will struggle to find a site with a downloadable set of 49's historic results. I've had a look around, and the ones I found want you to specify a date or a month, then give you results limited to that timescale. Some just post images of balls, which is pretty useless. None of them are downloadable. Your passworded site probably was the best bet. Do you have to pay for access now?
