This is due to a problem with either your phone number you registered with or your password. First thing is to check here http://www.zaksenterprises.com/index.php?option=com_zaksapp&task=myLog and see what your logs show. if your log is blank this could mean that your phone number you registered with is different than the one in your phone. This can be caused by issues with Family Share accounts. For this you will need to contact an administrator. Otherwise you should see a password error which you will need to update the password stored in your wap manager account.
