PT 9.0.6 playback doesn't stop

[Luke BB]

Second time it happens, don't wanna format my Mac again, eh...

Pro Tools Playback doesn't stop, also using spacebar, enter and "0" on bluetooth numeric pad.

I'm running NOTHING, empty session only with click track, and another session with click track and Minigrand.

What can I do? I NEED Pro Tools NOW!

Macbook Pro 15" i7 @ 2.2, 4 GGB RAM. Mac OS X Lion 10.7.4, PT 9.0.6

Any solution, please???

Thank you


PS: I'm using the Built in audio device, not MBox or other aoduio interfaces. Till Saturday i hadn't problems, runned perfectly,.

PPS: Usually i plug the Ilok into a external USB HUB with power supply, and always worked fine till saturday...
I just tried to plug off the HUM and connect iLok directly on my laptop and seems to work.
So....what can I do to turn back to use HUB??? I need it, I have to connect keyboards, HDDs and pen drives...and iLok too!

Ok, maybe I've found the problem:
the engine was set (automatically...why???) on "Pro Tools Aggregate I/O"
Changed to MBox2...works great, changed also to "Built in"....works great too.
No stop.

Don't use Pro Tools Aggregate I/O!



If someone wants to reply, I'll be glad to listen/read other opinions.
Thanks everyone

Grrr!
Opened a session, start creating, and...problem not solved.
Seems laptop can't handle the playback, sometimes it stops playback after some seconds, minutes...semms under presure, but nothin is open.
Maybe hot temperature can afflict pèerformaces?
30 degrees, maybe less i think, is not so high, i think!

Seems to be solved plugging the USB cable of my Roland A800pro directly into my mac instead on the Hub. This way Pro Tools goes right.
Don't know why, but i wanna discover what cause the crisis...

Hi ... did u finally found the problem ? i don't think it was only a usb problem was it ? cause i'm experiencing the same issue ... or something like that ... i launch playback and sometimes the playback doesn't stop... i can do all i can, no one protools function react... and when it suddenly stops to play after like 30 sec sometimes ... all i did during it was playing react suddenly (ex, open a plugin, modify a volume.. etc)
