Game crash on loading

[JadedKitteh]

I'm extremely new to using mods, and haven't any experience with coding, but am interested in learning, so any help with this issue would be wonderful! I think I installed the Explorecraft mod for 1.12 correctly, but when I launch this version, it crashes, with the following information:

---- Minecraft Crash Report ---- // Surprise! Haha. Well, this is awkward.

A detailed walkthrough of the error, its code path and all known details is as follows:

not 100% sure but I think your forge is very outdated?

Latest: 14.23.5.2847 Yours: 14.23.0.2529

try updating at least to the newest recommended and let me know how it is

Thank you! I will give that a try!
