Can not select from my own MV. Please help.

Question

Hello Gurus,
I have created a MV with following clauses
CREATE or REPLACE MATERIALIZED VIEW "OWNER_NAME1"."MV_Name1"
BUILD IMMEDIATE
USING INDEX
REFRESH COMPLETE
AS
SELECT column1, column2 .... from table1,table2
where .....
I have logged in to DB with the 'owner_name1' schema itself which is the owner of the MV.
But, when I try to select from the above MV. It gives error "Ora-00942 table or view does not exist"
I can see the same under 'user_objects' view as an object of owner_name1 schema.
Could you please help me in understanding where I have gone wrong?
DB - Oracle 9i on unix platform.
Thanks in advance!
Abhijit.

Oh! I missed to mention the exact steps followed by me which created error for me,
viz.
1) I have 2 Database and their users as follows
bq. i) DB1 in local server - 'localUser'
bq. ii) DB2 in remote server - 'RemoteUser1' and 'RemoteUser2'
2) 'RemoteUser2' user in DB2 has 'select' privilage on table 'RemoteTable1' of 'RemoteUser1' ( both are remote DB's users ! )
i.e. select * from RemoteUser1.RemoteTable1; --works okay when logged into RemoteUser2. no synonyms are created hence using schema_name.table_name convention.
3) Logged in to 'localUser' in DB1.
4) Created a DB link 'local_to_remote2' in 'localUser' schema ( in DB1) to 'RemoteUser2' schema (in DB2)
i.e.
create database link local_to_remote2 connect to RemoteUser2 identified by password using 'connection_string';
DBLink was created successfully.
5) I could select from the tables of 'RemoteUser2' using DB Link. (by logging in to 'localUser')
i.e. select * from RemoteUser1.RemoteTable1@local_to_remote2 ; --- gives me expected output. no issues!
6) Now, I created below MV in 'localUser' ( no need to tell in 'DB1' )
the exact syntax I used is as follows,
CREATE or REPLACE MATERIALIZED VIEW "localUser"."MV_Name1"
BUILD IMMEDIATE
USING INDEX
REFRESH COMPLETE
AS
SELECT column1, column2
From RemoteUser1.RemoteTable1@local_to_remote2
where condition1
and condition2;
The MV was created successfully, and I could see it as an 'Valid' object of 'localUser' schema.
i.e. select * from user_objects where object_name ='MV_NAME1' and status ='VALID' --- tells that above create MV is an object of owner 'localUser'
But, when I try to select from the said MV. it gives me error "Ora-00942 table or view does not exist"
i.e. select * from MV_Name1; ---- neither this
select * from localUser.MV_Name1; ---- nor this works :(
Even when I try to drop the same MV it gives me same error. :(
Could you please suggest me anything so that I will be able to select from MY OWN MV ?
Please help Gurus.
