Some errors are caused by IE10 Protected Mode. When avoid IE10 and Protected Mode the problem is gone.
Must do this before seeing 601 error.

Set -> Internet Options -> Security to
Custom level -> Medium -> Uncheck "Enable Protected Mode"
F12
Browser Mode: IE9

Before using Mog Station might do the trick.

Don't forget to "Turn on Protected Mode" after completion.

"401 error dialogue" invites user to try again instead of this warning.
"Please also note that once an authorization has been rejected, that form of payment cannot be attempted again for a full twenty-four hours, and any further attempts before that time will automatically be rejected."
So everyone of us is lured into 601 error.
Zarno, thanks. Did this work for IE10? I got the 601 first try with this today, and I tried a few more times, so I'm guessing I'm locked out of my account for at least 24 hours, maybe more, so I'll try again tomorrow, but can disable this before I try, if that will (for sure) eliminate the 601. Thanks.
