Can’t install wordpress via fps

I’m creating a website with wordpress. I’m using Filezilla. They gave me a domain and I logged in on filezilla, I had to erase the folder that was already in ther with the domain bc I dragged and dropped the wrong files (actually I don’t know why, but I could not remove, it gave the error 550, so I renamed it and created another directory with the site adress). OK, I installed wordpress but it was asking me the pasword to the fps everytime I tried to install any plugin or theme. Sometimes it didn’t stall so i did it directly on filezilla. Still it was working. But I erased the folder on filezilla so I could install it agains and see if this error would go away, but now it’s not working. When I try to go to the installation page it shows the message “Not Found
The requested URL /wp-admin/install.php was not found on this server.”. I don’t get what’s happening… I’ve installed another site the exact same way.
I just took a look on the DB’s and the old site db looks like this:

The db of the new site is looking like this:

The wp tables aren’t there… why? I didn’t do anything different.
