Need help timeout expired when restoring database using SQL Server 2005 Management Studio

Here's my script:

RESTORE DATABASE [database 2.2] <br>
FROM  DISK = N'F:\database Backup\database Backup 20.Mar.2015\database2.2.bak' WITH  FILE = 1,  NOUNLOAD,  REPLACE,  STATS = 10
GO

result:

10 percent processed.
20 percent processed.
30 percent processed.
40 percent processed.
50 percent processed.
60 percent processed.
70 percent processed.

Msg 3013, Level 16, State 1, Line 1

RESTORE DATABASE is terminating abnormally.

Msg -2, Level 11, State 0, Line 0

Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

Please help I need to restore my database. I am using SQL Server 2005 Management Studio.

Thanks
