Hello. I've seen that many people have issues with installing 7.3. Here is a guide for any turbulence you get when updating, and specific help for specific crashes.

If your crash contains something similar to:

'''Description: There was a severe problem during mod loading that has caused the game to fail

cpw.mods.fml.common.LoaderException: java.lang.NoClassDefFoundError: fossilsarcheology/client/model/prehistoric/ModelTriceratops'''

You have not installed LLibrary 1.4.0-1.7.10. Please do so.

If your crash contains something similar to:

[18:49:53] [main/INFO] [STDERR]: [java.lang.Throwable$WrappedPrintStream:println:748]: java.lang.NoClassDefFoundError: net/minecraftforge/fml/relauncher/IFMLLoadingPlugin

You have the incorrect version of LLibrary-1.4.0. Please make sure you re-download LLibrary 1.4.0-1.7.10 not LLibrary 1.4.0-1.10.2.

If your crash contains something similar to:

'''Stacktrace: at fossilsarcheology.Revival.preInit(Revival.java:82) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)'''

Please uninstall CoFH core, this is a bug we are currently trying to solve.
