Were you able to "downgrade" to a previous version? Sorry, I was upset with the feedback from the modders that I hadn't come back here. In the luancher, on the Modpacks tab, there is a drop down box next to "Private Packs" and under the "Maps" tab. I just changed it from "Recommended" to "4" and then my game seemed to work again. Again, sorry about not getting back to you sooner. Take it easy.
