on the Web Admin Panel, go to Domains -> Web and look up lifelinemobile.com - is the Status 'active' or 'changed' ? If 'active', click on Edit. Write down what you have on that page for "Web Directory". It should look something like /home/username/lifelinemobile.com
Make sure the username selected is the same one that you are using to log into FTP with. Then login to FTP and check to make sure you uploaded the files to that directory. If the username and the directory check out, and the status is 'active', I'd contact support. If it was 'changed', it takes some time before it becomes 'active', and it should be working once its 'active'.
