I can play online :(
I need the last patch
When i click online then he give me this adress http://team17.com/patch but is doesn't work ! :(

Try http://wwp.team17.com/main.html?page=comm&area=_down_patc

Also http://wwp.team17.com/patch.html (redirects to the above page) - note both addresses start with "wwp", not "www"
