I got render and RAM preview problems. help?

i got render and RAM preview problems with after effects! please help me

when i started on a project earlier today the RAM preview was failing and it stoped making a preview after about a second, when i hit the RAM preview buttom again it continued to load and stoped again after a half second, and it continued to do that till it wasn't loading at all, just playing the same thing up even doe it haden't loaded the whole composition! BUT if i moved the (thing you see where you are on the timeline in need of a better name) it started loading a little more and then it stoped again.. so after alot of problems and moving i managed to make a RAM preview of the whole composition..

now the real problem: when i was done with my project and i was going to reender i did like this: i added my composition to the render queue, chosed my render settings and started to render, after exactly 37 frames it stoped and no window or anything poped up, the only thing that was telling me something was wrong was the render status, and it said: ''failed at 0;00;00;37'' that's not even a second! and BTW when i render after effects only uses 12% of my 6GB RAM memory.. i dont know what to do! i've tried other render settings but the same thing happens! can anyone help me?

BTW i'm swedish and only 14 so i might misspelled something..

Start here and make sure that you understand how RAM preview is supposed to work first:

What version of After Effects? Have you installed the recent updates? What operating system? What kind(s) of source footage? Has this ever worked before? What other software are you running? Do you have any third-party effects or codecs installed? Are you rendering with OpenGL?
What are your Memory & Multiprocessing settings? Are you using Render Multiple Frames Simultaneously multiprocessing?

What exact version? You dodn't answer my question about the updates.

> it was mainly call of duty footage, resulotion 1280 x 720 and 60 fps.

What format and codec?

You didn't answer my questions about memory and multiprocessing.

after effects CS5 64bit version 10.0

i havn't installed any updates.. but after effects worked fine 4 days ago, so unless there's new updates i guess that's not the problem.

format MP4, i dont know about the codec.

i dont know what memory and multiprocessing settings i have, but as i said.. it worked fine a couple of days ago

You may have done something with your CoDecs on a system level which may relate to your whole capture setup. Could be the CoDec itself, could be the OpenGL and hardware acceleration settings it affects (in addition to running the game). Impossible to diagnose from a distance, but if something that worked 4 days ago doesn't work now, something has changed, no matter what. So if you did change something in your graphics card settings, installed a CoDec pack or a new version of FRAPS or whatever capture tool you are using, undoing those changes might resolve the issue...
