Please someone know how to resolve this

I had free hosting on a server, in exchange I had to put banners, but recently I can not access the ftp anymore

I had an access denied, and TotalN team can not be found anywhere they disapeared, they still have a web site but no one answer me.

I removed everything on dabase exept few stuff.
But I would like to remove the files too. I don't know what to do with this.
