I'm just starting modding so I am absolutely lost. I installed the latest version of forge for 1.5.1 and I was able to get into the modded title screen initially but soon afterwards I was met with the error message, " net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from mercurius_updater (mercurius_updater)." I would always get to the loading screen but it would crash soon after starting. I tried deleting the mercurius updater folders in the minecraft folder but it didn't help. The entire crash report reads as follows: ---- Minecraft Crash Report ---- // Surprise! Haha. Well, this is awkward. Time: 12/29/19 2:12 PM Description: There was a severe problem during mod loading that has caused the game to fail net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from mercurius_updater (mercurius_updater) Caused by: java.lang.IllegalArgumentException: URI can't be null. at sun.net.spi.DefaultProxySelector.select(DefaultProxySelector.java:147) at

I hope it wouldn't be to much of a burden to walk me through what to do. I use Windows 10 if that is any help.
