I tried to use 0.3.1 of bigtangle-wallet.bat, but I got the exception below.

Caused by: java.lang.NullPointerException
        at net.bigtangle.core.MessageSerializer.makeBlock(MessageSerializer.java:54)
        at net.bigtangle.ui.wallet.Main.main(Main.java:743)
        ... 11 more

Any initial arguments are required?

I didn't try bigtangle-bin.zip because the antivirus detects it's suspecious.
