Guys, I had the same problem(s) as listed above.
Positive balance, 0 balance, approved 1000 LAT, then 200 LAT...

The dev was updating the affiliate panel website.
Anyway, yesterday I contacted him on twitter, and I was credited asap my balance on my wallet (+- 270LAT).
Look for the dev on twitter under Latiumcoin and have a chat with him, request payment, they will do it.

Hope it helps.
