Sync Problems with Live 8

[veediawara]

Hi, I've been using Ableton Live forever. I upgraded from Live 7 to Live 8 in september. I've had many gigs (Dj sets) and no problems. Since January 2011 i started to get problems during my live set with syncing. Loops that i 've used forever are now not in sync. It seems that the mastertempo (the click) changes on its own. My loops continue to be in sync but any loop i try to play on top starts 1/4 or 1/8 note later. And you never know when it's gonna happen. I've tried playing the same loops for 5 - 10 minutes and there's nothing logical as to when it happens. the loops might be in time for 5 minutes, the next time they are in time for 1 minutes, then the click changes. It's driving my insane.
Does anyone else have this problem - or better does anyone know a simple solution to my problem? I don't remember changing anything in the settings and i haven't bought any new equipement or programs. The problem just appeared during a gig.

What is your global quantization set to?

global quantization is set to 1/4. I've just tried playing a loop that's perfectly warped. It's on time with the click for quite a while (4-5 mins) then all off a sudden the click goes into the 2nd (1/4 later). So any loop i try to add just starts 1/4 later and there's nothing i can do. No external equipement attached.
It's so weird and frustrating.

In Clip properties, under the Loop. there is a Start and Length. What is the Length set to??

Also, does this happen on a fresh set, or is it on a specific set that you have saved? If you look in Arrangement View, are there any odd automations or anything?

I'd like to bump this as I'm experiencing the same issues on a project. Did this ever get sorted?
