My Hive wallet is acting strange

[teddy5145]

Long story short, I only had about 0.0001 inside my wallet,then i just received my payment from this forum ( 0.018 btc )
And a few hours later i bought windows key on this forum too (0.013 btc)
Mathematically speaking i should have around 0.005 in my wallet,right?
But somehow my wallet didn't display the correct amount

And the problem is, i can't sent my remaining btc (0.0005)
whenever i tried to sent my btc to someone it says


{"status":"fail","data":"Could not push your transaction!","code":500,"message":"Did you sign your transaction?"}

Any guess what happen to my wallet right now?

Thanks for reading
