hmmm, okay, so when you are looking at the listing, and you click Save this seller from the right side of the page, or when viewing the seller's "My World" ID page and you click Add to favourite sellers the left side (those both take you to the same next page), if you unclick anything you are asked to subscribe to, then at the bottom press the 'save' button, what do you get next? Your 'Saved sellers' list, but do you get a dialogue bar at the top which says "Your preferences have been saved"?
How many sellers have you saved? Try this, - pick one, any one (the top one?) and find a listing this seller has, then save it in your Watch List. (This is so you don't lose the seller completely). Then from your Saved sellers list, delete that seller. Then try to save a new and different seller. If it works, that means your list was full.
