Hm, your Transaction Log shows you are still getting orders via "PayPal Pro (DirectPayment)" checkouts, so that indicates everything is fine at our end and with the integration setup between E-junkie account and PayPal Pro, therefore, any problems with completing that type of checkout would have to be at PayPal's end, and without an exact error message or error ID number from affected buyers, we have nothing more to go on that could help get you pointed in the right direction with PayPal support. :^(
