Erm.. Hi again, not sure what to do

Well Shiann there's no need to redownload the script files unless you actually developed your site in offline mode, on your old computer I mean. I do this before uploading/testing scripts on the internet, so I keep all the backups. If you have a 000webhost account already with configured Mys site, theres definitely no need to worry about losing your script files and database.
