Reset identity column values after delete and insert error in SQL Server

Hi,

SQL primary key IDENTITY problem

I have created a MS-SQL table as follows; 

CREATE TABLE [dbo].[UserRoles](
	[UserRolelD] [int] IDENTITY(1,1) NOT NULL,
	[Date_Time] [datetime] NOT NULL DEFAULT (getdate()),
	[UserID] [int] NOT NULL DEFAULT ((1)),
	[RegDate] [datetime] NOT NULL DEFAULT (getdate()),
	[Active] [bit] NOT NULL DEFAULT ((1)),
	[RoleName] [nvarchar](100) NOT NULL,
	[RoleDescription] [nvarchar](1000) NULL,
	[ModulerID] [int] NOT NULL,
 CONSTRAINT [PK_UserRoles] PRIMARY KEY CLUSTERED 
(
	[UserRolelD] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

PROCEDURE for date insert

CREATE PROCEDURE [dbo].[UserRoles_Insert]
	@LoginName nvarchar(20) = 'sampath',
	@RoleName nvarchar(100) = 'xxx',
	@RoleDescription nvarchar(1000) = 'xxx',
	@ModulerID int = 5
AS
BEGIN
	SET NOCOUNT ON;

	DECLARE @UserID int
	SET @UserID = (SELECT UserID FROM [SATHUTA-ERP].[dbo].[ErpUsers] WHERE LoginName = @LoginName)

	DECLARE @RoleDescription1 nvarchar(1000) 
	SET @RoleDescription1 = (SELECT CASE WHEN LTRIM(RTRIM(@RoleDescription)) = '' THEN NULL ELSE LTRIM(RTRIM(@RoleDescription)) END)

	IF NOT EXISTS(SELECT UserID FROM [SATHUTA-ERP].[dbo].[ErpUsers] WHERE RoleId = 1 AND ActiveUser = 1 AND UserID = @UserID)
		BEGIN
			SELECT -1
		END
	ELSE
	IF EXISTS(SELECT UserRolelD FROM UserRoles WHERE ModulerID = @ModulerID and RoleName = LTRIM(RTRIM(@RoleName)))
		BEGIN
			SELECT -2
		END
	ELSE
		BEGIN
			INSERT INTO UserRoles (
							RoleName,
							RoleDescription,
							ModulerID,
							Date_Time,
							UserID,
							RegDate,
							Active)
			VALUES (	LTRIM(RTRIM(@RoleName)),
						@RoleDescription1,
						@ModulerID,
						GETDATE(),
						@UserID,
						GETDATE(),
						1)
			END
	END
GO

After 

My problem was;

[UserRolelD] [int] IDENTITY(1,1) is not 1,2,3,4,5,….n

Thanking you
