Absolutely! You are allowed to use the Wizard to review hand histories after you have finished a session.
PokerStars and FullTilt prohibit the use of any ICM calculator while the poker client is running. The intent of the policy is to prevent players from using a software application to get advice on a hand while the hand is active.
The primary target of the new policy is a certain competing ICM program that offers real-time advice while playing. I have made it clear many times that I believe offering real-time advice is cheating. A FAQ in this forum clearly states my policy concerning real-time advice. I completely support the spirit of the new PokerStars policy.
In order to comply with PokerStars policy, the Wizard disables the importing of hand histories and the entering of custom games whenever it detects that the PokerStars client is running. You can still use the quiz mode while playing. PokerStars has approved this action.
In order to comply with the FullTilt policy. the Wizard will shut down whenever it detects that the FullTilt client is running. FullTilt has approved this action.
