Setup new Fixed Tax Rate Provider or reinstall all the tax providers?

By mistake I have deleted all the tax providers. does anyone know how to add it back or how to setup a new Fixed Tax Rate?

Execute the following SQL script over your database:

INSERT [dbo].[Nop_TaxProvider] ([Name], [Description], [ConfigureTemplatePath], [ClassName], [DisplayOrder]) VALUES (N'No tax', N'', N'', N'NopSolutions.NopCommerce.Tax.FreeTaxProvider, Nop.Tax.FreeTaxProvider', 1)
INSERT [dbo].[Nop_TaxProvider] ([[Name], [Description], [ConfigureTemplatePath], [ClassName], [DisplayOrder]) VALUES (N'Tax By Country & State', N'', N'Tax\General\ConfigureTax.ascx', N'NopSolutions.NopCommerce.Tax.GeneralTaxProvider, Nop.Tax.GeneralTaxProvider', 2)
INSERT [dbo].[Nop_TaxProvider] ([Name], [Description], [ConfigureTemplatePath], [ClassName], [DisplayOrder]) VALUES (N'StrikeIron Basic (US and CA Only)', N'', N'Tax\StrikeIron\ConfigureTax.ascx', N'NopSolutions.NopCommerce.Tax.StrikeIronTaxProvider, Nop.Tax.StrikeIron', 2)
INSERT [dbo].[Nop_TaxProvider] ([Name], [Description], [ConfigureTemplatePath], [ClassName], [DisplayOrder]) VALUES (N'Fixed Rate Tax', N'', N'Tax\FixedRate\ConfigureTax.ascx', N'NopSolutions.NopCommerce.Tax.FixedRateTaxProvider, Nop.Tax.FixedRateTaxProvider', 10)
