Always the first attempt at logging in takes me to an Http 404 page not found, I have to hit back and login again before it lets me in. Both IE 10 and Firefox 25.01 on Windows 8 Pro. Just to let you know. Have yet to try Chrome or my Linux box though. Once I actually get in it is flawless. Been doing this consistently since the PlanetX logo was added so webmaster check your http redirects.
Otherwise AWESOME!
