MPC and Pro Tools 8 sync

Hi guys, sorry for this I imagine a lot of people already asked about how to sync the MPC to Pro Tools. I have an MPC2000xl and Pro Tools 8. I already have been able to sync it with Pro Tools and I remember I had NO LATENCY at all, exactly on the beat. I have a AMT-8 and a Unitor 8 (previously I've connected it to the AMT-8, I just recently bought a Unitor 8 to have other 8 IN and OUT, the Unitor is without USB and it's connected to the AMT)

I can't figure out what's going on, I've spent all the night over it and in a few hours I must go to work, my eyes aren't open, I'm learning braille... anyway

With Ableton live works well Ableton always works at my home I get a bit of latency because Ableton uses Midi Clock, but I remember with MTC in Pro Tools I got no latency.

Well what happen? Seems totally out of sync, not only latency, seems like a sleeping drunk drummer, if I play with note repeat aren't 1/16 or 1/8

I can't also record the MIDI in Pro Tools, the "OnLine" icon (the one like a clock) blinks seems like it's not seeing the MPC, but I can't figure out what's the problem, in Ableton and Logic works, and I think I've set up the MPC properly, but probably I've mistaken something in Pro Tools, I don't remember exactly how to set Pro Tools up, I just remember there's something tricky

Ok, let me know
Thank you very much!

Well I read this http://www.akaipro.com/syncprotools

but, for example, when it says click on setup, session, put 30fps as midi code rate, till here everything ok, but than it says check the MTC box, there's any MTC box here and I don't understand why nor where it is....
