I'm been mining to the official sumokoin gui wallet for over a month now.  For the last two days, when I try to open my wallet, I put in my password and it is accepted.  The network shows synchronized.

However, it gets stuck at 'loading wallet'

I googled this issue and reddit said to run it with admin permissions.  I did that but no luck. 

I've not found anymore help online.

Has anyone else had this issue?
