looks like maybe your not getting the whole download, there should be some sort of message that things completed or they failed...I know that I am unable to get ANY of my modpacks to launch as well...I fired up the launcher today and NOTHING will work...It keeps telling me "your minecraft installation is corrupt, but has been cleaned Try to login again, if that fails close and restart the application" and of course I have tried that and of course I still get that message, as far as I know nothing has changed with my install of minecraft, java, or any of my mods that would cause the message...my logs show a particular severe error over and over again "Minecraft verification error" now since seeing this I did run out and upgrade to the latest version of minecraft but that didn't produce ANY different results...I am not sure what it is that can't be verified I can load up vanilla and play there just fine without any hitch but absolutely none of my mods will load....Im guessing this is a launcher problem? Im no java expert or a game dev but I do know that I am not even getting the Mojang logo screen...so I guess that means its launcher related right? don't wanna end up banned or with some weird avatar..
OH and in case anyone is wondering I do have my Antivirus software disabled, I use Avast
