SoapUI 4.0.1 Download broken

I am unable to download the soapui 4.0.1 for linux, it seems to take a very long time to write the last little bit of the file, but once its written I can not extract the zip, looking in the zip it has three items; META-INf (directory), xulrunner-iwindows-info (file) and xulrunner-windows.zip (file).

Not sure whats going on, but I can download 4.0.0 without issue
