Help synching mobile and pc

 
I've been using the demo for the past several months. Every time i try to get into the pc account i have problems with the password, which i reset today. Now that i'm finally using my pc it doesn't have the history of my tablet trades. My tablet doesn't have my user name just a number for the account, & that can't be accessed either on the pc. Any ideas?
 

Log in on your tablet with the new settings.

The account was probably generated when you installed the mobile application.

 
I just tried to log into the new account on my tablet. 1- the login on both the pc and the tablet receives only numbers- those i'm assuming are the account numbers. But they still don't work for my log in. (I have to use the email on logging in from this morning and it allows me to log in with my profile name and password. 2- on my tablet the log in is only numbers and the tablet does not even allow me to use letters for my profile  name. I'd like to keep the performance I've built on my tablet as it has been a good history and shows my theoretical profits.
