Can't create snapshot - HELP!

I'm on a 8.0.5 database trying to create snapshots from our production database on 7.3.3. Here's my DDL:

CREATE SNAPSHOT owner.table_name
TABLESPACE valid_tablespace_name
PCTFREE 5
INITRANS 1
MAXTRANS 255
STORAGE ( INITIAL 250K NEXT 250K MINEXTENTS 1 MAXEXTENTS 200  PCTINCREASE 0)
REFRESH FAST
START WITH to_date('23-DEC-1998 01:00:00', 'DD-MON-YYYY HH:MI:SS') NEXT trunc(sysdate +1) + 1/24 AS
select * from table_name_at_valid_dblink_name;

Here's my error:

ORA-12028 - snapshot type is not supported by master site.

I've tried complete and force refresh. I've verified that my database link works. Can someone please help?
