coin control -> inputs -> click on (un)select all)
that will show you the total amount of coins you can send.
I'm off brb later
yea did that, its the exact same situation as described above.. seems like some balance is stucked or something..?
EDIT: got an error "Error: The transaction was rejected. This might happen if some of the coins in your wallet were already spent, such as if you used a copy of wallet.dat and coins were spent in the copy but not marked as spent here."
I didn't touch the wallet.dat file at all how is there a copy of it >_>
