You just have to wait longer.I've gotten this issue too. I already attempted the link at the beginning a couple times, and tried redownloading the modpack.
Pastebin: http://pastebin.com/8WkubNqJ
Having this exact problem. Modpack is downloaded but i get this error whenever i try to run itIs anyone else getting "Uexpected end of ZLIB input stream……" and an error extracting natives, I haven't seen it in any paste bins, and its happening right under your dirs mk'd problem.
Update Java. You shouldn't have Java 6 anymore.hy i have also problem with the Horizons modpack. When i get to the Mohjang screen, the minecraft client is close up. It didnt say anything just close. I deleted, redownloaded everythin even Java, but i get the same problem again and again. I have 2Gb RAM so its not a problem and Unleashed is working fine. This is my crash report, what i get : http://pastebin.com/5XT8jK5b . I hope someone can help me bcs i really want to try out this modpack .
