Yes, a couple of people have had the same problem. My only solution was reinstalling the wallet. But you have to delete the folders AmsterdamCoin and AmsterdamCoinNode otherwise the problem persist. I have tried several things but i didn't find another solution.
Is someone does find another method let me know...
The only problem is will I lose all the coins that I have staked in the past couple of weeks because I haven't backed up the file that is used for staking. I know this because Solaris is the same wallet and the team said to back up the file for staking in case something happens. I forgot to do it with AMS so I'm guessing that I have lost all them coins I have staked.
That's only the case with cold staking. Our next release (also Solaris) will have a fix for that.
Okay thank you Kees.
Lucky it wasn't a whole lot that I staked and just to make sure, what NLGer posted is the right way to fix the wallet from being stuck on loading as I don't want to lose my coins, its not that I don't trust this person I just like to know from the dev himself.
