Now that you mention it, try using 32 bit one. I personally never experienced what you're reporting so it's either specific to your machine/client/java setup or specific to a region you're travelling through, but if it was the latter then likely much more people would be subject to it.
Alternatively, if you have a trully trusted friend, you could give them your acc info and ask them to log in from their pc and see if they get same issues or maybe they can move you out(and you'd know for sure it's related to your setup).
