HTC Eris :: Changing Boot Animation - Zip File And ADB Shell

I have the VanillaDroid ROM installed on 2.1 v2. My phone is rooted. But I don't like the boot animation that came with the ROM, so I decided to change it. In every tutorial I've seen, people mention a "bootanimation.zip". However, I can't find it anywhere on the phone. But I did find the "bootscreen" folder in "/system/media/" with the bootup animations in it. I assumed that if I swap out the animations for the new ones, it would work (reasonable enough right?). Not really. Apparently, I deleted everything in the bootscreen folder, but when I try copying stuff into it from the memory card, it can't find any directory on the memory card through the "adb shell" stuff.

I know the folder with the bootscreen animations and stuff exists on the memory card, but apparently the shell commands say it doesn't exist. So now my phone boots up with no animation or sound. Its nice to have a quiet boot, and it does seem to start up a little faster, but I want a boot screen again. I know if I reflashed the ROM, it would come back (or at least should). But I don't want to have to reset and redownload all my apps and stuff, especially since I have just got everything the way I want. Is there anyway to get the bootup animations back without reflashing? And if I would reflash, since its the same ROM, would I need to do a factory reset?
