Julio try the curse launcher if you haven't yet. I have tried the mym and ftb and both of those don't work for me but the curse one does work
looks like your running a resource pack [1210] [Client thread/INFO]: Caught error stitching, removing all assigned resourcepacks java.lang.NullPointerException at lumien.resourceloader.ResourceLoader.insertForcedPack(ResourceLoader.java:36) ~[ResourceLoader.class:?]
Well i am done. now every time i try to re download the modpack without the resource pack it always fail
Again I don't know too much about this laptop because its not mine someone gave it to me and i have no idea of how to check that out
