My best advice on this one would be to contact Tech Support and describe the issue to them. They've always been very quick to respond to my help tickets.
On the other hand, if you're talking about the Events notice that you're not set up properly for eBay notifications (I've forgotten exactly what the wording is), that can be ignored.
Otherwise, check with the tech guys! They should be able to get it worked out for you.
Good luck -
