Ever since the new Launcher came out I've not been able to use Alice mods or go on the Alice server. The mods on the launcher conflict and the game freezes on the Skcraft screen and after 5 mins says that Minecraft has crashed. I'm not sure what's happening, so I will accept any helpful comments. See my error report below:
It's sometimes because old versions of the client are conflicting with the new ones, sk89q did his best to fix it, but there are sometimes few problems... In your %appdata% folder, delete ".skcraftalice" and the launcher configuration file (wich should be in ".minecraft" so if you don't care, delete it too) and then re-update, if you don't delete the configuration file, it'll think you have a minecraft.jar, then it'll try to get it to update it (I don't know why) but as there is no more any file, it won't work, that's why you must reset the launcher configuration file
that's a goddamn id conflict, change the id that it says its conflicting with in the config of that mod in you ./minecraft/config/ folder to another id inside the range of 4096.
I had the same problem, and I found the solution, I though helpful and friendly to tell it, I think it's a natural reaction, pleased to help you
