read some other guy's post and found one can do shift-F6 to bring up the console. Below is the console output. I have also tried to uninstall (1.0.0) and re-install again (1.0.3) but same problem

When I tried to go to the URI with my Firefox, it asks me if I wanted to create a new account (it doesnt display the old accounts).
Console output:
