I decided to get a mod for my Minecraft Realm. I downloaded Minecraft Forge and the mod. I reopened Minecraft, tried to enter my Realm, and it wasn't there. Red letters appeared on my screen, stating:
TRY RESTARTING MINECRAFT
I restarted Minecraft several times. I removed every single trace of the mod and Minecraft Forge. I tried again and it still didn't work. I could not log onto a non-Realms server, either. I repaired Minecraft on Mojang's website, but it still doesn't work!
