Rift

So, I just finished the page for my modpack and went to try and install it through the Launcher. It installs correctly, but when I click the play button, it appears to be downloading all the assets and then closes the launcher as if the game will start. Then about a second later the launcher reopens. I've tested with 2 other official packs, and they run just fine. I have tried increasing the amount of RAM the launcher uses, uninstalling the pack and reinstalling, changing Java versions, and nothing has worked. I've had my friends test it and it doesn't work for them either, and now I'm just totally stuck. Logs: http://pastebin.com/Z1khgRYn Pack Page: http://www.technicpack.net/modpack/voidlocke.876247 [B#347] 2016/07/25 15:33:50 [INFO] [15:33:50] [main/ERROR] [FML]: There is a binary discrepency between the expected input class ahu (ahu) and the actual class. Checksum on disk is 782b2e42, in patch 746fe971. Things are probably about to go very wrong. Did you put something into the jar file? [B#347] 2016/07/25 15:33:50 [INFO] [15:33:50] [main/ERROR] [FML]: The game is going to exit, because this is a critical error, and it is very improbable that the modded game will work, please obtain clean jar files. Keep in mind, the pack worked perfectly normal when I launched it through the normal MC launcher and not the Technic launcher. UPDATE: Okay, I think I figured it out. All my mods are running on 1.7.10 and so is Forge. However, Technic installs Minecraft 1.7.9 onto the pack because for some reason there is no option for 1.7.10. Sooooo, I'm not too sure of where to go from here.
