密钥在有效期内但却激活不了

[LenJKiang]

我上个月购买了Greenhub的一年全球套餐的key，并成功激活了，但今天我要使用Greenhub时，发现我的客户端突然变成了未激活状态，并且使用之前的key尝试重新激活但无法成功，请尽快解决。
Last month, I purchased the key of Greenhub 's one-year global subscription and successfully activated it. However, when I want to use Greenhub today, I found that my client suddenly became inactive, and I tried to reactivate it with the previous key but failed. Please solve the problem as soon as possible.
