These guides will provide the guidelines on how to change the contract data of your account.
You can only change your contract data if all the mark records linked to your account have status “Incorrect” or if you have no mark records linked to your account. If you do have verified mark records linked to your account and you still wish to change your contract data all mark records will be assigned status incorrect and will be validated again. The mark records that were previously assigned status verified will most likely be invalid after this validation.
We strongly suggest that you create a new account if you already have verified mark records linked to your old account.
