Hi Daniel,

There are currently 49 items listed under your account.

Barring any further help from ebay, may I suggest you take a copy of all those listings, titles, descriptions, prices, etc, because if you are unable to ship any of the possible  purchases, your account may be suspended in due course, and then you will lose the ability to at least view your listings.

You may then go about relisting those items under one of your other active accounts. 

You may be able to check if any of your listings have sold in the last little while by searching under completed listings for your items. 

By the way, I really empathize with your situation, as it is the kind of dumb thing I have done myself elsewhere, mainly because I have an unhelpful aversion to updating anything.
