It seems that you are just using the 'getbalance' command wrong, don't put "'*' 0" at the end.
like this:
bitcoin getbalance
You might be missing transactions so try running:
bitcoin -rescan
then:
bitcoin listaccounts
I did rescan a couple of times already, and I'm using the getbalance command correctly.
But thank you for showing some interest, it is appreciated
EDIT : Using listaccounts is a good suggestion actually, gives some more insight, results posted below
