URGENT! I can't build with Unity

Hi,

I was trying to get my Game Music to work when I stumbled on an Unity Error with the File (Editor)
(Build: Windows x86_64)

Please help me ASAP!

I had a similar issue before. When working with a partner from a different timezone, they sent files that to my computer, appeared to be 2 hours from the future. For some odd reason Unity cannot build with assets from the future. Unfortunately, you might just have to wait a few hours until it passes like I did! Other than than, edit the files to reset the date, or change your computers time? Goodluck
