I would like to post as another person to the list of those who still can't log in. I just tried a few minutes ago.
Here is the background info.
First, my family has 4 accounts all on the
same credit card. 3 of these accounts work (my wife and I, and 1 mule) and 1 other that does not. All accounts have been active and in good standing for a long time with no break in service. The non-working account does have a different SE login than the other 3 that are working.
I have tried this from both Windows Vista and Windows XP machines with the same results.
On the non-working account, here are the screens I get when I log in:
Screen 1
Screen 2
Screen 3
The account has a Security Token, if that makes any difference.
I hope the details provided may help Square resolve the issue.
Thanks,
-Ari
