Hi, thanks for replies.
I registered yesterday (no credit card etc details, just very basics) and prepared a Family Tree in advance as per Ancestry website instructions. However today, even by following the "correct" links from the site, it didnt appear to be offering anything.

I then started a new tree hoping that might help, at first it didnt seem to, then I started seeing the actual transcribed Census information which I presume is the "free" access, albeit still quite limited with no actual scans etc visible (which I hadn't expected to be honest).

Hope this helps, keep trying and if in doubt try bashing the pc, if nothing else I find it makes me feel better, good luck.
