Can't access early actions on timeline

[theat1851125]

I'm doing a project with a LOOOOT of brush strokes.  Thousands and thousands.  Sadly, some of the brush strokes were not the color i want them at this point...but accessing brush stroke 100 of 14,000 seems impossible.  I give plenty of time for them to load, can only get about 2,000 back.  And even those, if I try to click on one to alter any of it's attributes, it won't open.  So, I started deleting the strokes manually and redrawing them the way I want (tedious), and it caused my computer to crash, and a warning saying this:   

After Effects warning: Error parsing properties list from memory

You are going to run into resources problems using that many strokes.  Your options are to segment your work in pre-comps so fewer strokes are used on a single layer. That's just the way it is. Paint is not optimized or efficient at this point and that's the only work around that I know of. You may even have to render and replace some of the comps.

Thanks for the help....I was afraid that was the answer! Now I know for the future at least!
