Problem with importing package

I have been using unity for a few years now and I purchased an asset a few years ago and at the time had it in my project. I have since upgraded and started over and now the asset will not download and I am including the error that it gives me after it attempts to decompress. I have tried to import in both my current project as well as a new project with the same. alt text

Maybe the file is corrupted. Did you try to contact with the asset author? Did you tried to dowload and Import anbother asset to be sure is only this asset? The asset has been updated from last time you downloaded it ?
