SAP Crystal Report stuck on "Please wait while the document is processing" but not hang

My Sub Report works until I add stored video parameters and linked it to my Main, It got stuck on "Please wait while the document is processing".

The Main Report Preview Works but if I run the report it doesn't

Here's my stored procedure for both reports:

ALTER PROCEDURE[dbo].[usp_MainReport]            (                                      @StartDate DATETIME,               @EndDate DATETIME            )            AS  BEGIN
select * from users
END

ALTER PROCEDURE[dbo].[usp_SubReport]            (                               @StartDate    DATETIME,            @EndDate      DATETIME            )            AS  BEGIN
select * from users
END

Is there a problem with my SAP Crystal Report?
