Broken unity asset import

Ok, so i needed some top notch particles for my game, and i went onto the asset store to find one. I found one that looked really great, but the import was too large. Now Unity is stuck importing and i cant finish my game. Any help? Here’s the link to the asset: Unity Asset Store - The Best Assets for Game Making

What does “too large” mean? I’ve imported significantly larger assets than the one you linked. Are you out of disk space?
