Voltz Update Fail (can't fix the usual way) in Voltz Discussion Posted April 18, 2013 Right, I've cleared the Cache, set build to 1.0.0|1.4.6 (lowest) and allocated 16GB of memory. I've deleted and re-downloaded the technic launcher a dozen times. None of it works. Keeps getting up to 99% or "Checking for Minecraft update" and then saying: Update Failed. Weeks I've been trying to get on Voltz and non of the other packs are working either except for Tekkit.Someone, anyone, please help.
