I doubt you will get any useful help if you don't post more info.

It seemed to me that the row estimates were not so far off that I would
call it a statistical failure; you can try increasing the stats target
but I'm not hopeful about that.  My guess is that you will have to look
to revising either the query or the whole database structure (ie,
merging tables).  We'll need the info I asked for before we can make
any recommendations, though.
