Program won;t start

[Michael Hopcroft]

I've downloaded the update and the upgrade and followed the instructions. However, I must have done something wrong because when i try to start the program, even with the update, I get Java errors and the program doesn't open.

Is HeroDesigner.jar what the file name needs to be for the program to work? If now, what should it be?

It needs to be "Hero Designer.jar" not "HeroDesigner.jar" -- basically, just replacing the old file of the same name (which you should have deleted).
