QQ can not stay on line?!

[Sam in Hi]

Dear Sir,

When I add my QQ account into the account list (2008QQ), it works only for a
few second. >_<
Then the server will tell me that " the QQ account has been suspended, 
Since Your QQ number may exist in unusual circumstances, 
And has been restricted login protection, need to be activated to log in."
您的号码可能存在异常情况，已受到限制登录保护，需激活后才能正常登录

Can you tell me how to solve this problem?
Thank you very much. And you've done very grate job to build this software,
help us a lot and save a lot works for us.
Thank you again.

Sincerely,

Sammy Yu
