The main problem with this coin is that the published source code doesn't match the functionality of the newer Windows executable. Most likely the source was updated, and a new Windows client was compiled from that source, but the source changes were never committed to github.

It's possible the changes were a hard fork or perhaps an enforced version, because clients compiled from the source refuse to talk to the newer Windows clients.

So we're left with an orphaned Windows client - it can never be updated because we don't have current source. It also means that exchanges will not be able to compile a client that works with Windows clients.

It may be possible to reverse engineer the Windows client to figure out what changed (and why) but that's going to be a real headache. The other possibility is to move forward from the source that's available, but this will be a hard fork, so it will mean that anyone running a Windows client will probably need to resync from scratch.
