Try clearing your internet cache. Also go to files.minecraftforge.net/mirror-brand.list and tell me what that shows you.

Should work fine. We removed one of the mirriors because they were 404ing.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

The .list file can't be opened because i'm on a mac and I can't find a program to open it. I cleared my internet cache and that didn't help.


Just use a text editor to open it...

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.
