When I extract the files, I get the valid folder structure:

wen-travel-pro.5.2.3.zip >> wen-travel-pro >> theme files

I have tried a variety of troubleshooting events and these do NOT work either:
1. Used a different computer (MAC vs. PC)
2. Used different browsers (Chrome, Safari)

Please let me know any other ideas. Otherwise I may require a refund.

Thank you for your help!
