im trying to redownload a modpack i was using, i tried adding shaders (they were already included in the pack) but it wouldnt load and it closed the minecraft tab on its own. when i tried to continue playing and pressed "play" on the launcher it wouldnt launch so i decided to try deleing the modpack altogether and then redownload it but it only gives me the option to install or delete pack. any ideas as to whats happening ?
