Diff Backups - Urgent pls help

I have a full Backup and a diff backup on a SQL 7 database
I have restored the full backup with NORECOVERY option sucessfully in a SQL
2000 server
When i try to restore the diff backups its gives me a error
Server: Msg 3136, Level 16, State 1, Line 1
Cannot apply the backup on device 'Z:\MS SQL
SERVER\Backup\AVAWEB\AVAWEB_DIFF_20050111_203101.b ak' to database 'AVAWEB'.
Server: Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.
-- Here is the command i am running
RESTORE DATABASE AVAWEB
FROM DISK = 'Z:\MS SQL SERVER\Backup\AVAWEB\AVAWEB_DIFF_20050111_203101.b ak'
WITH FILE=1, NORECOVERY,
MOVE 'AvaWeb_Data' to 'Z:\MS SQL SERVER\data\avaweb_data.mdf',
MOVE 'AvaWeb_Log' to 'Z:\MS SQL SERVER\log\avaweb_log.ldf'
Are you certain that you didn't perform a database backup between that db backup and the diff backup
you are trying to restore. I'd check in the backup history tables in msdb just to be certain.
