Cindy - which profile have you started with on the Unresponsive Profile Manager process? It's not something you can do at the Profile Manager level, so you have to start with one of the profiles you would like access to.
So once you've identified that profile, you should be able to do the initial steps - private message to PM, public comments on her profile, public comments on the profile you want access to. Then wait 7 days. Once that's done, then you can fill out the Unresponsive form.
I'm going to presume from what you've mentioned above that you've already added the initial steps, so what we need next is the actual profile where these messages were left so that we can direct you to the form on that page. Sometimes it can be challenging, and if it's a completely Private profile (living person) then it presents other challenges. So if you can help us by posting the actual profile you're starting with, then we can be a better help.
