You bought a Single Site license. If you try to activate your license key on more than one server you get that note about reached limit.
All of your licenses were or are active for wallstreettt.cn.
You do not need to purchase it again now since due to #QFIP-EN-816 it is valid until September 4, 2019 (the date of your first purchase +3 years due to renewals).
Do you want a refund? That would shorten the valid time to September 4, 2018.
