Error code 401 is a payment problem that has existed for FOURTEEN MONTHS. They obviously know about this problem because it is one of the most popular items on this support thread & they offer digital time cards so you can still play .. but there is no work around if you want to buy items off of the store or want to hire extra retainers.

There are several people wanting to give SE their money but SE won't fix their payment system, this is inexcusable. PLEASE make your game work the way it is supposed to. I won't put up with this, there is no excuse for anyone wanting to consider themselves a professional company and won't fix a problem as basic as "PLEASE! LET ME GIVE YOU MONEY!"
