World crashes every time I try to enter

[Pureheartbear]

Hi there. I'm hoping someone can help me. I've tried a few of the things like updating java and that didn't work. Here is the error code. Thanks

I'm going to assume that you are using windows:

%appdata%\.technic\modpacks\tekkitmain\config\forge.cfg -> Open forge.cfg, change the following values from "=false" to "=true":

    # Set this to just remove any TileEntity that throws a error in there update method instead of closing the server and reporting a crash log. BE WARNED THIS COULD SCREW UP EVERYTHING USE SPARINGLY WE ARE NOT RESPONSIBLE FOR DAMAGES.
    B:removeErroringEntities=false

    # Set this to just remove any TileEntity that throws a error in there update method instead of closing the server and reporting a crash log. BE WARNED THIS COULD SCREW UP EVERYTHING USE SPARINGLY WE ARE NOT RESPONSIBLE FOR DAMAGES.
    B:removeErroringTileEntities=false

Try joining your world again. If it is fixed, turn those values back to "=false".

[Pureheartbear]

Yes, windows. Do I just change the two instances of false? I noticed there are more than two. I changed the two above and it didn't do anything.

I just tried changing all and it didn't help.

If it did not help, then it is a possibly resolved issue with Better Player models:

http://mods.curse.com/mc-mods/minecraft/221939-more-player-models#t1:other-downloads

Download the 1.7.10b file and put that in your mods folder instead.
