Problem with a script to create a DB

hi, I am writing from argentina, and the question is beacuse I have problems to create a new DB from a script, in SQL Express Edition
when I execute the query the following erros appears:
Msg 5133, Level 16, State 1, Line 1
Directory lookup for the file "c:\dce05\dce05_ejemplos_estrella1_Data.MDF" failed with the operating system error 2(El sistema no puede hallar el archivo especificado.).
Msg 1802, Level 16, State 1, Line 1
CREATE DATABASE failed. Some file names listed could not be created. Check related errors.
Msg 911, Level 16, State 1, Line 2
Could not locate entry in sysdatabases for database 'dce05_ejemplos_estrella1'. No entry found with that name. Make sure that the name is entered correctly.
Msg 2714, Level 16, State 6, Line 3
There is already an object named 'Productos' in the database.
