why?

why cant i log in under the preview grid?

Specifics would be nice to help us help you with this. If you get an error, please let me know the error--also, if you recently changed your password, try using an older password, because the "snapshot" of Preview Grid is taken from an earlier time. Please email me at [email=torley@lindenlab.com]torley@lindenlab.com[/email] with further details if you'd like, and of course you can contact support about it.
