Facing issue with Web Tours Creating Customer Profile

Hi , 

I have installed and using LR 12.02 version for Practise purpose .

When i have entered all the details to Create  Profile in Web Tours (First Time Registring) , it is showing an error msg :

" Your username is taken. Please choose another (usually adding a personally significant number to the end of your username will create a unique name) "

Web tours is not taking any data after creation of profile , i also tried to login once but the Profile have not created.

Please find the error attachment and do provide one solution for this.

Thanks,

Sreekanth
