Yesterday I added a conf file, got connections, and started to sync. It got to 12 days behind then stopped syncing. Still have connections. Anybody know what's wrong and how to fix it? Thanks.
For the reasons - see the post right above yours ^^^
Or just let me guess - that is because of nobody mining this, because developers did everything by design to prevent the people from mining the coin...

Nobody mines == chain doesn't move forward.
That was regarding the "whats wrong part".
Regarding to "how to fix it" part: if you want your wallet to sync - start mining (but be prepared to get nothing in return).
