Probably the credits were the reason. I saw credits exhausting too fast so the forum was activating and deactivating accordingly. Now that the forum has credit, you should get credit in your account. However, I am a newbie here so not much aware of the reality.
There are credits for this forum, but they are as it is for the last 10-12 days, they are not exhausting nor are they being given to the users here. I guess admin is too busy with something to pay attention to this. I hope they are okay~!
