I am having this exact issue. I downloaded the file and the username and password are correct. but it will not let me in. Out of curiosity, where are the username and password stored? 
I scrapped everything and started all over again and I am still getting the same reqults. The login is not working.
I am only testing out powerstore3, but you can access it here:
www.powerstore3.com
