Hi folks. This is a newbie question, but I am having a heck of a time. I have experience using AE7(CS2) but when I try and use it at home, it will crash during render...every time!
I have a PC, Pentium 4, plenty of HD space and 2 GB of RAM. Also have a tough time getting Premiere to work. Any suggestions?

When does it crash? As soon as you hit render or half-way through?
Check your memory settings in Preferences. Be sure you have Disk Cache checked and specify a folder for it to use, preferably on your media drive. Also, be sure to check Prevent DLL Address Fragmentation (I may have the name wrong for that but it's something close to that).
Search the archives, there are some articles on the Cow that should help.

have you noticed the ram usage when ae crashes...?
at the top of the render queue, ae displays the ram usage. the default ram cache setting is 60%, if ae is crashing when it hits that ram cache limit, then you can try to force purge the ram cache with the 'secret' preference.
to get the secret pref, hold the shift key and select any ae preference from the preference list. then select the pref pulldown from the preference window, and at the bottom should be one labeled secret. select it and set the 'purge every xx frame' to a value less than where you crash occurs... so if it crashes at frame 200, try setting it to 150. this will force ae to clear the cache prior to hitting the full point (hopefully).

What kind of footage are you using at home? Is it different from the footage you use at work? Here's why I ask:
Dave's Stock Answer #1 For Current Footage Woes:
If the footage you imported into AE is any kind of the following -- Native HDV, MPEG1, MPEG2, mp4, m2t, H.261 or H.264 -- you need to convert it to a different codec.
These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.
In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.

Thanks for the responses...
Dave - So far all I've tried is fairly generic .mov and .avi files. Seems like it should be able to handle those (as well as a truckload of others) without problems. Thanks for your help!
Kevin - I haven't noticed any problems with the RAM during render,. but I'll keep an eye on it and follow your advice if it seems to be the hangeup. Thanks for your help!

steve's probably right, qt7.4 displays the exact symptoms you are describing...
but just to clarify my earlier post, when i was talking about ram cache during render, i wasn't talking about ram previews. i was talking about rendering. when you render from the render queue, as it renders you can see the ram usage at the top of the render queue. it slowly builds up until it hits the ram cache limit that is set in the memory preference. at that point ae should start clearing the older cached frames from the ram cache to to make way for new cached frames. sometimes ae has trouble clearing the cache during a render and crashes. setting the secret preference to clear the cache at a set interval can often clear fix this issue. it will slow the render down a bit, so i wouldn't use it all the time, but when needed it can get you through a render....
