Guys I know a fix for the connection error. Basically when I got the error on my account I then tried it on my other account and it worked.

So if you get the network errors just try it on a new different account

If anyone knows how to get this to stick please pm.

Okay I'ma give you the biggest hint if the dupe 'worked', this is the dead giveaway before you play the game to make it stick. If your little armory credits are the same as the low level account you know it should stick, if not, redo.
