Feral Heart

It worked fine last week, but now whenever I try to play, it tells me I need to download the new patch. I go download the patch, it still won't let me in. So I X it out and open it up again. still won't work. I check my username, and my password, it's all right.
So I uninstall the lot. And then install it again.
All I get for these efforts is the rather persistent message, "Please download the latest patch from feral-heart.com"
Grrr.... I have the patch....
help?
