There is lots of lag in Voltz, so i decided to downlad Optifine. Not reading information on how to do it on the internet, thinking it was the same for Vanilla and Voltz, i put Optifine in the Minecraft jar, not the Modpack one. Now whenever i launch Voltz it shows a white screen without even reaching the Mojang screen. I wanted to reinstall Voltz but i can't figure out how to do it. I went on Voltz Options and pressed reset, but it didn't work. I tried to delete Technic launcher and redownload it, but it's the same launcher with the same modpacks. I love Voltz, and really want to play on it again. PLEASE HELP ME!
