Navionics Chart Installer - has been down all day

I'm trying to update my chart/freshest data for my sd card.
However, the navionics chart installer site is down.
The error I receive is "The chart installer is currently down for maintenance. Please check back soon".
I checked it at 730 this morning and again at 4:30 and its still down.
If someone from navioncis could chime in it would be appreciated!

I recently upgraded the sd card, and now when I turn on my HDS gen 2 units, they freeze up on bootup.
I'm running what I believe is the latest version of lowrance operating system (45.135).

I have to turn them completely off using the dash panel (turns off all power to the boat), remove the sd card, then power the units up, they work fine.
You can't turn the HDS units off when they freeze up. It never leaves the bootup screen and the power button has no effect.
???

Did you get this solved? I know Navionics webapp updates were working last night (and much faster than normal, and a new point release as well).
Regarding the card, did you try both slots (if you have a 2-slot model)? I seem to remember in some cases it has to be in a certain slot (the "+" slot I think). MIght not be your issue but worth trying, I've had the same issue before and don't remember exactly how I solved it, might have just redownloaded which it sounds like you are trying.
