Błąd - Unable to launch the application

Próbuję otworzyć plik z rozszerzeniem jnlp i wyskakuje mi błąd "Unable to launch the application", wie ktoś jak rozwiązać ten problem? Mam JRE SE 6 (Update 18).

A szczegóły ?

Chodzi mi konkretnie o tę aplikację http://www.ariscommunity.com/aris-express, błąd to "Unable to load resource: http://download.ariscommunity.com/activation.jar", a jeśli chodzi o szczegóły, to w zakładce "Wrapped Exception" jest coś takiego:
