Hello. I have tried various things to fix this problem of mine. I have reinstalled my graphics card drivers as well as updating/reinstalling java, adding the legacyjava.jar fix into the mods folder of my modpacks, and, of course, reinstalling the modpack and the technic launcher itself. However, my issue remains. Whenever I hit the play button for any modpack (an official technic one or a community one) it crashes immediately. Is there something I have not tried? What can I do to fix this? Thank you.
