I go to Marketplace and then I click "Misc" and then I click "Post New Thread" and then I click "click here to upgrade" and then I fill name, address, country, etc and then from drop down box I select $30 and then I click on "Order" and then I get :- Couldn't find valid marketplace thread ID. So, how do I proceed ? I need to sell service where I run Bing Ads campaign for people. I know the $30 needs to be paid AFTER thread is approved, BUT how can thread be approved if I get : Couldn't find valid marketplace thread ID. I am really stuck in a LIMBO. I have sent PM to a moderator or admin, too.
