Hi,
The reason for this is likely that you're logged into Windows as antony when you're starting loadUI, as loadUI will attempt to use the .loadui folder in the current users home folder (C:\Documents and Settings\<current user>\.loadui). You can override this behaviour by specifying -Dloadui.home=C:\Your\Path\Here\.loadui on the command line, as you seem to have already figured out.
Regarding the error you're getting, can you try starting using only the -Dloadui.home parameter, as well as the other test related ones and see if you still get the error? If you do, can you check the if there is any error above the one you posted?
