HI, I believe this issue is a know one and is probably related to no having the unlimited strength Java cryptography extension installed (which are needed if you live outside the US).
More recent versions of Java should fix this. What version of Java are you running and do you have the unlimited strength Java cryptography extension installed? See here for links for installing depending on your Java version. [1] Thanks, Justin 1. https://en.wikipedia.org/wiki/Java_Cryptography_Extension
