Hello Andrew,

thank you for your message.

First of all please read these hints about how to restore a backup: http://help.websitex5.com/en/v14/pro/backup_ht.htm
or try to import the project using a valid previously created iwzip file.

In case of difficulties you should please send me all project files, so I can check if it is possible to recover it. Go to the project folder, which is usually under C:\Users\yourusername\Documents\Incomedia\WebSite X5 v14 - Evolution (yourusername refers to your Windows account) and create a zipped file of the whole project folder, then upload it online using this service: https://wetransfer.com/ . Finally, select the link generation and write it here, so I can download the file.

I'm looking forward your reply, thanks.
