Technic Pack Not Working

When the latest technic update came out my Technic stopped working. I launch it from Technic Launcher like all my friends with the difference that theirs work. I chose the update at the top of the manual selection list and have given it the maximum ammount of memory space possible then laucnched it. It comes up with a white screen for a second or two then another java screen titled 'Hello' apperes for second then dissapers and, with the technic launcher still running in the background, it freezes. I have the window running while I was writing this and about 5 mins before that and it has done nothing. If anyone has any idea whats causing this or how I can fix this please reply to this post or PM me.
