Same store displayed many times in market Place

[AromeCity]

If someone remove an old store and install a new store will the extensions purchased under old store will can be installed under the new store?
-------------------------------------
Also when I am trying to connect my store to market place I am getting this error message, even though I can directly log into the market place account.

{"error_title":"Login Error!","error_text":"You are not logged in. You will be redirected to login page","show_dialog":true,"reload_page":true,"error_code":401}

Any ideas why is that?

Did not have any problems connecting to the store till re installed the software.
