Paypal unable to process

I linked my paypal account through the api integration.

When I tried to page the message said:

We cannot process this transaction because there is a problem with the PayPal email address supplied by the seller. Please contact the seller to resolve the problem. If this payment is for an eBay listing, you can contact the seller via the "Ask Seller a Question" link on the listing page. When you have the correct email address, payment can be made at www.paypal.com.

Have you seen this before?

Hello,

I have not yet encountered so far such error. But based on the error given, it states that it has something to do with the email address set. Probably they have upgraded their system which unlike before will simply accept payments whether or not the email address exists. This may be a security feature they added in order to look-up the account first so for it to land in the proper wallet before they accept the payment. Can you check the email address you have set if there is a typo in it or confirm that the email address you have used exists in Paypal?

Thanks.
