cswa exam code error

Hie everyone.im trying to take my cswa test and have entered my voucher code I received from solidworks yesterday through text, but unfortunately it keeps saying

PLEASE REVIEW YOUR ORDER
the coupon entered is invalid. You may try another coupon, or proceed without entering a coupon.

The code is a genuine code as I am a subscriber. Am I doing anything wrong or do I have to wait for a few days,

Thank you all
