Splash: recv failed

[CobraA1]

I keep getting this error:

Splash: recv failed

Further investigation reveals the following from the web start launcher (when trying to launch it manually):

Exception:

This is after completely uninstalling Java and reinstalling it, and after a reboot afterwards.

In addition, trying to download and launch the installer jar directly:

D:\Downloads>"c:\Program Files (x86)\Java\jdk1.6.0_14\bin\java.exe" -jar minioninstaller.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/jdesktop/layout/GroupLayout$Group

Any help would be great.
