The 1.1 patch for The Witcher 2, which was expected today, has been delayed til tomorrow.
According to CD Projekt RED’s blog post: The good news is that the patch is ready. The bad news is that we have encountered some problems with the server infrastructure, making downloading DLCs impossible. We want to apologize to our fans for not meeting our target of delivering the patch last night. We will update you when we know more.
So, remain patient. The patch will be coming soon.
