Difference between PT and account balance

[aaharty]

Hey,

Im playing on the iPoker network at the moment (Chilipoker) and am wondering about a discrepancy between poker tracker and my account balance..

My account balance is at 508.16 (having deposited 500) but on poker tracker im up 40.43. Is this a fault with poker tracker or some extra rake iPoker is taking or....????

Thanks for any help..

P.S. PT definately has all hands played and have not played anything other than hold'em poker (i.e. blackjack, omaha)
