hi,
Would you mind going online and try to get some hires skins downloaded again?
I've enabled some logging for when you download skins, so that perhaps we can get a clearer picture of why your skin downloads are failing.
Just so you know, I've just tried it myself using your account and that worked fine. You'll be credited back the 'wasted' skin-downloads of course.
And finally some quick questions :
-Do you use some proxy server to access the web?
-What firewall do you use if any?
-Which anti-virus software do you use if any?
Thanks
