The Second Life 1.3 Preview is now up and open again! After our update yesterday we found a severe problem with the transfer of textures and inventory items. That problem is now fixed, and Preview is up for your enjoyment.
You can find the installers for the 1.3 Preview at:

The automatic updater should work correctly. You may get a warning that 1.2.104 is already installed -- that's OK, just install over it.
As always, please let us know about any bugs that you find using the bug reporter.
Enjoy!
