Hi. We're at a Code Club and trying to install the Forge client as well, but it fails after trying to download the libraries. Looks like a Forge server problem, since everything else works perfectly here. Both Windows and Mac users get the same error. One of our Mac users also got *really* slow download speeds when getting the forge jar-file, like 15 minutes on 3,2 MB or something.. And we're on a top-notch connection here and everything whizzes along just nicely.
We tried working around it by copying the libs from a computer that had Forge already installed, but to no avail.
Hope somebody can look into it and find a solution soon..
