Upgrading to webmin 1.401 makes virtualmin disappear (on Solaris)

Hi,

in the homepage of my Virtualmin (on a Joyent Solaris Accelerator) a new update was signaled: webmin 1.401. I clicked for installing, all went well (from what I could read on the page) and in the and it said: upgrade completed.
Then, a lot of 404.
Re-logging in, I get the standard Webmin interface, no Virtualmin whatsoever.

Please help!
