Getting kind of annoying now, so I'm just going to help you. The only difference in that table is the sEmail and nAge column, of which neither you need, so you can:
a. remove those columns from the PHP registration script.
b. do what I said before and look at the registration script and recreate the columns, not that you need to anymore since I told you what they are.
c. use the SQL script I made for you which simply just adds the new columns you need.
Code:
ALTER TABLE tUser ADD sEmail nvarchar(90) NULL, nAge tinyint NULL
d. or just use the SQL script (below) I made you for you which this drops the table and recreates it with the correct columns and data types.
Code:
USE [Account_CN]
GO
ALTER TABLE [dbo].[tUser] DROP CONSTRAINT [FK_tUser_tUserAuth_nAuthID]
GO
/****** Object: Table [dbo].[tUser] Script Date: 20/09/2015 9:54:47 PM ******/
DROP TABLE [dbo].[tUser]

For the record, I restored the database, with a different name and it worked fine. Also you do not need to restore this specific database, as far as I am aware it's exactly the same one as I released just with these extra columns which are used for the registration on the website.
