Correction of Reply Messages

[PD]

Dear all,

Sorry for cross post... since I doubt about which area of this question.

I just create one account call test for duration 300 second / 5 minutes.
After the maximum time reached, I logged by the system out. When I try
to log in again, the reply message display is "Your maximum never usage
time has been reached"

Seems that I have some correction for the message (take out never), but I
do not know how to do it.

Can some one let me know where to edit the above reply message ?

TIA

PD
