I have posted this same “frowning smiley” problem at G3/Playshare GPWA forum; emailed Jon-Jon with no reply. Maybe their emails are not working either.
Yes, even if you had downloaded their images, the URL is not correct.
Man, this sucks royally. I even just tried to install one of their “new” banners —- same problem.
You are correct that it gives the impression that my site was hacked, but from my perspective someone must not have liked the marriage between G3 & Playshare at their own office and hacked there system.
