I was recently working on a project in After Effects CS5 and did "something" and now when I RAM PREVIEW I'm only able to render 23fps even though the animation in my comp will be 30 secs. I have it set to LOOP and it just loops the 23 frames. This is extremely frustrating. Please help!!

it sounds like the endpoint for the work area got shortened, so you are not previewing the entire comp any more (typing an 'n' will set the work area's endpoint to the cti, conversely a 'b' will set a new beginning-point).

you can either grab the work area endpoint and drag it to the end of the comp, or hit the 'end' key on the the keyboard and then type 'n' to set the endpoint to the end of the comp.

It sounds like you only have enough memory to preview 23 frames. Without additional information about your system, OS, AE version, comp settings and footage used, that's about all anybody can say. Except for Kevin, who frequently thinks of the unthought-of.

So get busy and cough up the details, okay?

I'm working on Windows 7 with 4 gigs of ram. It had nothing to do with the end points on the CTI. Comp settings are:

Preset: HDTV 1080 24
Width: 1920
Height: 1080

Pixel Aspect Ratio: Square Pixels

Frame Rate: 24 fps

Resolution: Quarter (I lowered the resolution after reading that it could be a problem and it worked. I've just never had to lower it to this much before. I usually do a third or half and have no problem.)

with a duration of 26 seconds.

After Effects version 10.0

[Rob Moore] "I'm working on Windows 7 with 4 gigs of ram"

...and there's your problem. You don't have anywhere near enough RAM to really take advantage of AE 10's new 64-bit capabilities.

I'm having a friend who works in IT, and whose husband runs Adobe products on a new Mac Pro build me a brand-new Windows box for home (I'm typically a Mac guy). I was thinking I'd like 32 GB minimum, but she's only run across motherboards capable of 24GB. I guess it would be okay, but I'm thinkin' I should have a more capable motherboard.
