"An error occured while trying to acces the tradepost: Server ID not found"

1
Hello,
a friend of mine bough a premium month for the server.
So in order to do this, we added the server on his own steam profile linked to FT (Friend). I precise, the server was administrated with my STEAM profile linked to FT(Admin).
Then, he got premium and 24H later, mod wasn't active on the server. Then we noticed it was active on his FT profile but not on mine. We tried to active and waited for 10 minutes ... nothing ...
Then i tried on (stupid) thing .... i deleted the server from my FT profile (Admin) ... and we tried to desactive and active again Tradepost Mod ... now an error is displayed ingame. (see screenshot)

Can you help me ? I think it refeers to ID on your own service, and we i added again the server on my Admin profile, i got a new ID ... :( cant find the old one i deleted..

TYVM
