Hello there,
Here is the latest version of the Restrained Life Viewer (1.20.2) with the new "adult-compliant" flag (Linden Lab have modified their login servers and in consequence every third-party viewer has to be updated, or have "Adult" replaced by "Mature" in the top menu bar). There is also a crash fix for when your viewer automatically reattaches a locked item that had been kicked off by another one, and a workaround @tplm.
Grab it here :

Have fun !
