I can't see the meaning of words

I use the free version of Lingq, and I have reached my Lingq limit. However, whenever I click on a word, it says “Oops to continue creating unlimited LingQs, you will need to upgrade”. It never shows the meaning anymore, it just shows that message.I don’t want to create Lingqs; I just want to see the meaning of words. Does anyone know if there is a way to fix this?

It is possible to invite a friend. Any new user who refers to you during the registration gives you some extra lingqs.
