AssetBundle error

I’m getting the following error when attempting to download an AssetBundle from my server (via WWW class):
Failed to decompress data for the AssetBundle

Does the AssetBundle need to be built a certain way in order to be downloaded from a server? I’ve tried Uncompressed and Compressed and neither one worked. Any thoughts?

Bump.

Anyone know what causes the “Failed to decompress data for the AssetBundle” error? Has anyone experienced this before?
