technicpack bugg

[joop2345]

Hello everyone my name Is joop

I decided to play a modpack today, which I tried,

its downloading and after it it started,

there came up a white screen

and it said tekkit classic not responding

and its the same with every modpack i tried

I got it also on the normal minecraft launcher.

Can someone help me fixing this so I can play minecraft and modpacks again?

Ty,

Joop
