[update failed?!]

What i did was 1)set the memory to 16 gb 2)cleared the cache and it worked

How do you set your allocated memory to 16 gb? Mine only allows me to go up to 1.56 GB

[voltz not working]

when ever I go onto the technic launcher and log in with voltz or tekkit light it doesn't work and my account is valid as i can play tekkit classic i have java 64 bit please reply and help me

Same Problem.

My Technic Launcher is stating "checking for minecraft updates" as it has been for the past 20 minutes AFTER the 5 minutes it took to install the zip files and everything. The Voltz launch screen has been a blank white box the entire time. There was a brief moment (within first minute of launch) that a box titled "hello" was present, but it disapeared once I clicked on it's blank white window.

Help?
