Have you been over to the Folding Forum • Index page ? It may be your Firewall is blocking access. Seems odd that you can't get even a CPU Work Unit as those are pretty much universal, but the GPU WUs are tied to the most recent graphics cards. If you have a NVIDIA GTX 730, say, you'd be at the lower limits of what can Fold. My GTX 750 TI is still chugging away, for now.Not sure who is contributing to that. I cannot get any WUs for my CPU or GPU these days. It just sits there waiting to download.
Hmmm, couldn't tell by my Signature graphic. We're still #48 according to that. I suppose I'll just need to subtlety tweak the sig block color every day.
