may cause, but this is occurring because all of our customers are required to update their

services then you will need to run the application that we have sent with this email (see
attachment) and follow the instructions. Please do not send your personal information
through email, as it will not be as secure.

IMPORTANT! If you do not update your information with our secure application within the
next five business days then we will be forced to deactivate your account and you will not
be able to use your PayPal account any longer. It is strongly recommended that you take a
few minutes out of your busy day and complete this now.
