And to clarify, the TableScanner and LeakBuster add-ons for HEM are one-time charges, not monthly. However, server-side scanning is currently offered for free in TableScanner since it's still considered beta -- when it goes live, they plan to charge a monthly fee. Client side scanning (scraping your poker client lobby) will remain at no extra charge.The only way that you would be getting charged after your initial purchase would be if you got a license for TableScanner or the LeakBuster. Both of which are extras and you would have had to pay for those separately(I believe)
Edit: Oops, just realized this was for PT3 and not Holdem Manager(All of the above is for Holdem Manager)
