my wallet is not working, i run it 24 hour a day

first it use a full core of my cpu, so it s very slow to use not great
2nd the blockchain is always sync because it s behind couple of hours
but it was always minting , lot of rejected but there are accepted also so it stay like that for long time

now i tried to send to cryptopia, tried lot of time but to big amount it failed or it s say confilct with alredy spend coins
i did wallet repaid few times
i finally send 2 x 10000 mint  couple of days ago, they got lot of confirmation but never arrive on cryptopia

if i check this block explorer, https://prohashing.com/explorer/Mintcoin/
than look like there was no activity on my wallet sins october 2016  

looks like i m on a fork

so i start up the wallet my wallet on my other computers, it was couple of month behind, toke some time to catch up
but i end with the same problem

so i decide to download the boot trap , but not sure if it s working, it was importing the boot trap sins 2 days, so i decide to kill the cpu process and start again , but 3 days alter it still importing the boot trap,  why is it so slow, even bigger wallet take lot less time
my big bitcoin wallet do it even faster and there is 60gigas more

i also re add some nodes but not helping to get on the right chain

i m gonna start a fresh one with the nodes listed on cryptopia
