Installation on Ubuntu 11.10 fails

Hi,

i've been working with Aris Express on Windows for a while now. When I tried to install it on my Linux box I struggled with this exception during the installation process:

java.lang.SecurityException: attempted to open sandboxed jar http://download.ariscommunity.com/expresslauncher.jar as a Trusted-Library

I checked the URL mentioned in the exception and it turns out that it is not existing. Is there any way to get Aris Express working on Linux?

Thanks,

Stephan
