Sorry this isn't very useful. I'm just posting to say that I have the same problem. Do you ever see the admin panel? I never see anything. I just type in mystore.com/admin, and then it hangs for about 20 seconds, and returns to the log-in page.
I'm going to write up my own in "INSTALLATION AND CONFIGURATION" because I have never been able to access the admin panel since I installed. I even tried re-installing.
