I have a trail version of aftereffects CS4, that had expired a long time back, however I faced the following issues:
During Rendering or export in full resultion(Full HD) it crashes.
While editing a video to drag pointer from on fram to another, it very slow.
My system is properly built, I have a 1GB grafic card Nvidia, 8 GB ram, 3.2 GHZ processor, and 1T hard disk 7600RPM but Im using a 32Bit windows 7 operating system. however I have noticed that Aftereffects uses only 3.24 RAM, Im quite dissapointed at this point that all the capabilities are not yet into aftereffects coverage, I tryed mutli processing and it even make the program rendering while export or during preview slower!!!
I do require a solution, I cannot give up on aftereffects and planning to purchase the full version of after effects CS5, but as i noticed in many forms that the software is still into these issues and no solution has been made, therefore I will not invest on this software if the issue remained the same.
looking forward for your resoultion in this matter,
I'm sorry you're running into rendering and performance issues with AE CS4. Do you mind reposting your question over on the AfterEffects forum? I'd move it over for you but it appears I don't have the proper admin access. Thanks and good luck!
I know this doesn't answer your question but I'd just like to point out that 32-bit Windows only supports 3-4GB of RAM
