I am new to ETH so I will try to be respectful of those who are supportive of it. However, if I may suggest a few points?
I have no programming experience but I have had wallets get stuck in the past and ETH wallet was the same. All I had to do is stop and start the wallet a few times and finally loaded all the blocks. I have had the wallet running for 2 months and have not had one problem. I am using GETH.
