I was having the same problem you had. And what I identified while debugging the project is that it was running in its 32bits version in my 64bit version machine so the encryption and decryption of packets weren't working during the login.
It could match login and password from the DB, but when it ws supposed to enter, it just didnt work, like yours.
There's a dll in your project that takes care of the encryption using OpenSSL if i'm not mistaken. And that one is 32 bits.
I don't remember the name of the file and unfortunatelly I couldn't make this source work on my machine.
Maybe this information could help with the investigation.
