PUMS bookmark - troubleshoot

Hello - 

Might anyone know why a PUMS bookmark, created on the beta site, wouldn't function as expected?  My first use of PUMS worked well - I can still access my analysis using the bookmark.

Today I've created another table but the bookmark just defaults to the PUMS home page.  Hate to think of losing access to the site after much recoding and sweat!

Thank you.
