Cannot Find File ID 2 On Device 'xxx' - But It Exists!!

I'm following these instructions: http://technet.microsoft.com/en-us/library/ms156421.aspx

I run this restore letting it create the database. It works fine:


RESTORE DATABASE ReportServer

FROM DISK='\MYMACHINEe$BackupsReportingServicesReportServerData.bak'

WITH NORECOVERY,

MOVE 'ReportServer' TO

'G:DataReportServer.mdf',

MOVE 'ReportServer_log' TO

'J:LogsReportServer_Log.ldf';

GO

I run this command and get this result set, with the fileIDs in red.

then I run this LOG restore:


RESTORE LOG ReportServer

FROM DISK='\MYMACHINEe$BackupsReportingServicesReportServerLog.bak'

WITH NORECOVERY, FILE=2,

MOVE 'ReportServer2005' TO

'G:DataReportServer.mdf',

MOVE 'ReportServer2005_log' TO

'J:LogsReportServer_Log.ldf';

GO


Msg 4038, Level 16, State 1, Line 1

Cannot find file ID 2 on device '\MYMACHINEe$BackupsReportingServicesReportServerLog.bak'.

Msg 3013, Level 16, State 1, Line 1

RESTORE LOG is terminating abnormally.

I see file ID 2 identifying the log file. I've never done a restore like this - using copy_only and backing the database and log into separate .bak files, so maybe I'm misunderstanding something here.

Thanks for any help
