When I log into the server, everything seems to be fine. When i go to the School RP, the texturepack wont load for me, and only shows the mojang loading screen. I can walk (I hear the steps) and move around, but I cant see anything besides the red screen. Please help me.

Basically the game worked just fine until it said "The server requests for you to download the texture pack" I did so and it just kept lagging my game BAAAAAAD. After like 5 minutes it finally loads to show me a second of the game before forcefully kicking me out.

delete pls @Ducks
