let me provide some more detail to help....
I originally configured the s2 paypal options with my personal paypal account info (email & api info). when i got through the video tutorials i went a head and set up my business paypal account, came back into my settings and updated (only) the api info. when i did a test purchase, i discovered that it was paid 'from' and 'to' my personal paypal account. when i went back to the s2 paypal options, i noticed that i forgot to update the email address with the new business account email addy. i updated the email and this is when the issue started.
hope this detail helps. please let me know what else you might need to assist. thanks!
