I have a problem in registering the coupon code that I bought which refers to 6 months subscription. The system doesn’t accept it, its invalid.
@jazi_mitz - If you already have an account, you will have to enter your code at the bottom of the Account page. If you are still having problems, email support at lingq dot com with more details.
Thanks for the prompt response.

Also I tried to email your given email add (lingq.com) but its invalid.
