@Long Chung: i have read your posts and in my opinion you are too harsh and offensive the way you wrote them...
In that post a customer ask for support because af an issue.
Your comment (not deleted, it's there to read) is first of all "I suggest not to buy this software first".
To me, this should be enough to ban you from this forum!
So I think you must be more polite before criticize the others...
This is my opinion (I'm not an administrator, I'm a customer like you...)
