I just had a windows update yesterday and so I thought that I would try once again and open the AMS wallet and guess what it is now loading again and I was able to log in and start staking again. I don't know if it is windows that's the problem but I was trying for weeks and nothing but now the wallet loads again.
Tried to open same result. Stuck on opening page. Deleted all for a fresh install same thing. So no AMS at the present time. Too lazy to look any further for a solution.
