Dear EZSINO user,
Thanks for your email and we are delighted to provide you the relevant information.
I just opened www.ezsino.com some times could be slow but it shows no problem, however we suggest you the following.
If you read carefully the manual, the serial number is to register users that have not internet connection, and the typing is case sensitive.
Please do the following:
Go to http://www.ezsino.com/Agreement.aspx
Register an user name and password, then install the software again , when ask for serial just type skip, then install plattform and lessons to your PC and when is done restart and for the first time you need to be connected to internet, click on your ezsino patform icon on the desktop and use your user name and passoword you used to register on www.ezsino.com
To facilitate your setup we created an user name for you
Thanks for choosing EZSINO as your chinese lenguage partner.
