It looks like the database is still there, although I can't see how to export the data (the option isn't immediately obvious).
Good! Okay, here's how to proceed:
1) Above where the database is listed on that page, you should see a "hostname" and there should be a link adjacent to that for phpmyadmin.
2) Click that link, and login using the *database* username and that database user's password
3) When phpmyadmin loads, at the top of the leftmost frame, you will see a pulldown box with database names in it. Select the link for the database name that holds your wordpress blog data (in your case, "n-blog"?)
4) The left frame will refresh with a list of links representing the tables in that database, and the right frame of the page will now refresh with that database's structure displayed.
5) Click the "Export" tab at the top of the right-hand frame, and when the frame refreshes, click the "select all" link under the "Export section", and select the type of export you want (to reload the data in another WordPress blog, select "SQL) by clicking the appropriate radio button.
6) You can change any "SQL Options" desired, but the defaults should be fine (you may want to increase the "maximum length of created query if you have a large blog).
7) Check the "checkbox" labeled "Save as file", modify the "filename template" as desired (set's the filename for the export), and decide if you want compression ( your choice, for windows, use "zipped" if you want, etc.), and hit the "GO" submit button.
8) Your bowser should prompt you to open or save the file - select "save" and save the "download" to your computer.
9) Whew! If you did everything correctly and if all worked well, you will have that file on your computer after the download completes. Breath a sigh of relief, have a cup of coffee, and let me know that "It Worked".
How to load the data into another WordPress or access it in another way is another lesson. For starters, You may also want to "export" it in a different format, just to be "sure" or to have it in another format.
