Shi Streeter

I'm having nothing but troubles with this. I have 2 products that were never on Xstreet only on the Marketplace. I had them listed.. but some how they keep getting unassociated inventory.. and will not allow me to fix it. I'm very disappointed because on I paid for enhanced listing on one of the products. I followed the directions above to attempt to fix it..but when I do the search nothing comes up.
