Attainment asking for newer windower.

Attainment won't load. Error message I get is

Error: attainment - This plugin requires a newer version of Windower to run. (4004000)

Windower is showing I got launcher 4.0.5055.10847 and hook 4.0.0.35. I've restarted the app several time and it's not auto updating to the newer hook. Where can I get then newer hook.dll?

Nothing is wrong on your end, a mistake was made by us and a build of Attainment meant for the development version of Windower got pushed to the 4.0 update server. This should be resolved shortly.

Has been resolved now.
