[Plugin: Press This Reloaded] Getting 404 error when I click link on any site but mine

hey just installed this tonight
I am getting 404 errors whenever I click the Press This link on any page outside of my own domain.

I can press the link while viewing the wp backend or i can go to a visitor page on my site and click the link and it will activate the editor.

If I go to any other site I get a 404

The site I am trying it on is a subdomain.mysite.com
It is not a WordPress Network site it is a manual setup with its own install of wordpress 3.0.4

here is the link url it seems correct as to the domain and directory.

javascript:var%20d=document,w=window,e=w.getSelection,k=d.getSelection,x=d.selection,s=(e?e():(k)?k():(x?x.createRange().text:0)),f='https://CORRECT.CORRECT.com/CORRECT/wp-admin/post-new.php',l=d.location,e=encodeURIComponent,u=f+'?u='+e(l.href)+'&t='+e(d.title)+'&s='+e(s)+'&v=4';a=function(){if(!w.open(u,'t','toolbar=0,resizable=1,scrollbars=1,status=1,width=810,height=570'))l.href=u;};if%20(/Firefox/.test(navigator.userAgent))%20setTimeout(a,%200);%20else%20a();void(0)</p>
