Our server was down for few hours yesterday for maintanence and this was informed to all existing customers.

I've submitted an e-mail to the address. I also doublechecked and I was wrong that the non-LMS reporting version was having the same login problem, but it also doesn't show that anything has been reported to the ALS site.
