    This happened when i decided to try out a older version of ampz and then switch back to the new one. It tells me to look at a file for further info but i couldn't find it. The console says...
    1. "2013-04-26 18:51:16 [SEVERE] [ForgeModLoader] This version of FML is built for Minecraft 1.4.7, we have detected Minecraft 1.4.6 in your minecraft jar file
    2. 2013-04-26 18:51:16 [INFO] [STDOUT] A CRITICAL PROBLEM OCCURED INITIALIZING MINECRAFT - LIKELY YOU HAVE AN INCORRECT VERSION FOR THIS FML"
      I dont know how to fix this, please help...

    Did you do a force update? A force update re-downloads all the mods and minecraft and starts from scratch. Could you post the entire error log to pastebin?

    Will that reset my saves? If yes, is there any way to preserve them?

    It will not reset your saves... I think. You should always back them up first.

    hint, there in the saves folder of the mod pack your using.

    :) its fixed... thank you. 1 more question, is there a way to get the dungeon pack mod working with the launcher? It doesn't load when i add it.

    There should be, but we need the error log that it makes to fix it so it will. Follow the guide in Booker's signature to get it.

    Theres no crash, it just says "file already exists, cant add mod" it says that it is in the pack but when i load up a world its not there...

    Is the mod disabled in the launcher? Is this a new world or an existing one? When you load minecraft, before you load any worlds, check that it is listed when you click the mods button.
