Stephen,
We've removed the WFA 1.1.1 download link since WFA 2.0 will be available in the next week or so via the support.netapp.com downloads. Ideally, you would want to use the newest version. We can add your 'stephen2' NOW account ID to the list of folks who have access to the WFA 2.0 RC1 build right now if you want. If you have a specific need for WFA 1.1.1, please contact me offline at hill@netapp.com.
Best,
Kevin.
