One thing I've noticed and seems coincidental to my previous posts is that I get these error messages when someone sends me paypal outside of going to the website. For example - if I were to get paid through ebay for a paypal auction I would get an error message regarding that transaction, even though it had nothing to do with the site. I'm thinking to correct this I would probably need to set up a separate account (in it's entirety) for the site alone, and use the other for everything else. Hope my findings help someone else.
