Hi @mput - we are sorry about this. Please make sure that you filled your billing info properly. Also, would you try a different browser just to see if it works? If you still run into this issue, please let us know at support[at]lingq[dot]com.

@mput - You may also want to try switching your interface language to English and trying again. We have been experiencing some strange issues related to translations lately and, in the meantime, certain issues don’t happen if you have English as your interface language.
