Nope, not using a proxy as far as I know. Thanks for the link but it isn't my problem; I already have Spine (professional) installed and have been using it fine for some time, am just now attempting to download the update it keeps pushing but once it downloads the update it tells me to re-download and reinstall Spine because "launcher is out of date".
However, on the license page, upon trying to download the launcher, it gives me a broken page.
