If you are just upgrading from 7.01 to 7.1 you will need to run no upgrade scripts. You simply need to upload changed files listed under the documents subforum in the file called changelog.txt
There are lots of files between 7.02,7.03 and finally 7.1
Easiest thing to do is download the code. Unzip it to a directory. Delete the data and uploads directories. Delete the upgrade and install php files. Delete the header and footer.htm files. Delete the two config files. Upload what is left.
