WhatsApp 2.6.5917 and BlackBerry 9800

今天剛升級到 WhatsApp 2.6.5917,
但安裝從新開機後就上不了線了
出現這個訊息
"WhatsApp server connection failed.
If you have recently installed WhatsApp on another device, you will have to delete and re-install WhatsApp on your Blackberry if you want to continue using it on this device
this is what it shows up after it failed to connect"
我只有在這隻9800裝過WhatsApp啊
我也刪除重新下載, 重新安裝過了, 問題還是存在
有沒有人有跟我一樣的問題?????????
