Sorry for the confusion!
Update: I have been trying to schedule for the 23rd.. since the 14th. If you search on google for a while there is another forum with a post back in 2005 in which this occurred for almost a week.
Emailed MBA.com support staff -> (4+ days later) Their response was go to the website.
Found the hosting company for the MBA.com (subsequently GMAC) -> All systems were reported normal.
Called the customer service line (1st try) -> Call was re-routed through a few menus, eventually bringing me to a dead end that was disconnected.
Called the customer service line (2nd try, day later) -> Foreign call center I presume, she said "check the website tomorrow and hope for the best".. are you kidding? This was the line to schedule your test over the phone also. She then told me she couldn't even schedule the test on her side so apparently the whole system has been down for several days.
Tried on a Mac earlier this morning using safari-> same problem except it would let me a few steps with no glitch then at the end didn't have a 'register' button (tried to highlight the page hoping the graphic was hidden to no avail) there was however a new button that said Close which in turn did just that to all the progress I had made.
Edit:
Finally good news -> just tried again on a PC using Firefox 3.6 and it went through, and I have my confirmation in firm grip.
Needless to say, stress level is through the roof while trying to do final preparation leading up to next monday. I'm trying not to take this as an omen, hopefully no one else has had to deal with this, good luck!
