I just downloaded garage sale and am eager to get started
Well I encountered the problem of the PayPal address showing red on my listings, followed directions to delete account, key chain etc. restart many times, still was not working. The problem was my credit card was expired on PayPal although I have large credit balance in PayPal, so did nt really notice that this could be a problem. When I updated my credit card, magically seemed to work, after hours of trying to fix problem.
