Package error

[hsudblg (A)]

First and foremost, I want to thank the track/skin/bike creators for keeping this game alive for all of us to enjoy. At the moment, I have running into a small issue. When I attempt to transfer a track from WinRAR to my database folder, I am receiving an error message that states the package component of the .zip or .rar file is "corrupt." I thought this instance was strange because the other files transferred perfectly into the database folder. It appears to only be an issue with the package content file. If anyone has run into a similar issue and knows how to fix it, I would appreciate any assistance. Thank you!
