It looks like it's trying to use some method from Minecraft's auth stuff that isn't implemented anymore, or something (this isn't really my field of expertise). I'd be less bothered if OpenEye weren't listed on the MCF Mod List as working with 1.7.10.

We never tested it with 1.7.10 and never said it will work there. But thanks for report, I will try to fix that once things stabilize.

Ooh, thanks for that clarification (and for the quick response!). I had figured, since it was listed as working on the mod list, that someone had gotten it working and requested it be added.

Thanks also for your hard work.
