Question Maya Fluids Disappearing from viewport! Help!

Hi! I am using Maya 2012 and following Gnomon's master class by Wayne Hollingsworth, explosion lesson. I have a problem. A serious one and I am struggling on it since three days but no luck. Whenever I do a playblast, the sim runs for 20-25 frames and then fluids disappear from viewport. The timeline continuous to move forward but without any fluid on the viewport. I tried dong this several times. I even tried to render and cache the simulation but the problem persisted.
I thought may be there is a bug in Maya 2012 so I upgraded and tried in 2013 and still the same problem. Finally I took the original Gnomon's file and did a playblast and fluid disappeared yet again. (See the link below)
Now I am sure that there is some fault in my system. This has never happened before. I changed RAM, formatted my system and the problem is still there.
I would be really glad if someone can shed some light on this issue. Even the container is not huge. It's 100x100x100 with a base resolution of 100.

Yes there is no cache attached with the fluid container. And if I make a new file and play with the emitter then yeah fluid is behaving as it should.
I think this is must be something related to GPU driver. I will switch back to the old one and will check.

He means in the same scene, make a simple container and emitter and see if they work. If not something is definitely borked in your scene and you may have to reset it up.

Also try caching the fluid. That way you can always load it back in, or into a new container for rendering.

Sometimes things just go wrong and you need to rebuild the scene.

Yeah i had a cache but it was still borked :/ in the end i set the fluid container to global zero and re cached. Also scaling the fluid node up post cache does it no favours too :/
