I downloaded the Replay Mod for version 1.12-2.0.0-b7 and I also downloaded the latest Forge for minecraft 1.12-forge1.12-14.21.1.2389. When I launch minecraft everything works fine, I go through the forge loading screen before the main menu and i see the tabs, Mods, Replay Viewer, Replay Editor and Replay Center but when I try to join a singleplayer game my game crashes saying (in the main menu there is a crash report section):
Old Java version
Your Java is too old to handle secure connection to OpenEye server. Fortunately, client was able to provide missing data. Please consider updating to latest version.
When I go to my "Configure Java" and click update to latest version it tells me that I'm already in the latest version of java.
If needed, when I join a multiplayer server (which I plan not to really do) it tells me that I failed to connect to the server:
Internal Exception: java.lang.NoClassDefFoundError:net/minecraftforge/fml/common/registry/GameData
If I messed up on the spoiler because I'v never done this before here is the link to the crash:
