Marriott has changed how we access the SBA portal that is used to access several things including Marsha.  The process is simplified but requires changing both the webpage URL and the browser you use.  I have created a short video outlining the process, please note that I have condensed the video by removing sections where I was waiting for things to process or finish downloading. All told it took about 7 minutes but could be faster or slower depending on several factors. The new link you should use is https://sba2.marriott.com.
