update failed?! in Voltz Discussion Posted February 11, 2013 i basically cant do shit with my launcher. I try to launch Voltz, got the "minecraft and FLM fatal error blablabla" problem, then i try every solution here, but the one that seems to work the most (the above one) just wont work cauz it wont update. Yep, thats right, i just dont have any control at all over my launcher. EDIT: Ok, i managed to update like you guys said, but still got that f**king fatal error message. Its like the launcher cant access the files/folders it needs to updates. Well, looks like that for me anyway. jimmithesith, maybe if nothing works for you, you should try to contact somebody who made the launcher or someone who is really knowledgable on the subject, like direwolf20, the creator of the FTB modpack.
