[Resolved] LoadUI not starting up

Hi Everyone,

I have had LoadUI working for the past couple of days without any problems (apart from the initial install but that's another story)

The Java exception file shows the following:

Launch file

<jnlp spec="1.0+" codebase="file:." href="loadUI.jnlp">

Any help to get this working again would be greatly appreciated.

Kind regards
