NVU is a WYSIWYG editor - like Expression Web and Dreamweaver. It looks like you are trying to use FTP to place files from your computer to the server.
The first thing you say is
Are you getting an error message? if so, what is that error message? but then you go on to say
If I look at my site through 1&1 it's my old site.
which could mean that you are seeing a cached version of your site. if you are using AOL as your ISP - let's just forget it and wait.
If you are using another ISP and let's say Internet Explorer, you can try to press F5, or CNTL-F5 to do a hard refresh, this makes sure that your IE browsers goes out to the server to get a new copy of the files.
