Downloaded assetts wont decompress

I downloaded one demo yesterday (the skelle dungeon) and it worked fine. Today nothing I download will decompress. No messages other than the error line at the bottom of the Unity editor.

I tried several tech demos, a house scene and a couple of the free human models.

Edit: This is under Windows 7. Installed Unity yesterday and haven’t futzed with anything.

I think I figured it out. Yesterday I was using a local drive and this morning I was using a NAS folder. Guess the decompression won’t work across a network.

I have the same files that didn’t work earlier decompressing no problem on the local drive project.

Sorry!
