Error message - can't open project 
Autor: Kerry L.The software crashed while I was using it (I have version 14 fully updated) and now I can't open my project file. I have tried restarting my laptop.
When I try to open the project, this error message appears:
"The specified project is in use or has not been closed correctly. Do you want to continue?"
If I click 'OK', this message appears:
"An error occured while loading the project. (There is an error in XML document (0, 0).)"
I found this post on the support forum:
"If you receive this message, go to step 0 and select "Preference". The option "Project folder" shows you the path in which your WebSite X5 Evolution 9 project has been saved.
Go in this folder and proceed as follows:
1. Delete the "preview" and "upload" folder.
2. Delete also the files project.iwprj and metadata.xml.
3. Rename the file backup.iwprj into project.iwprj.
4. Open the program and select it from your recent projects."
I followed what it says and it was all fine until step 3 as there was no file named 'backup.iwprj'. All the other files were there, but not that one.
Please can someone help me to access my project again. Thank you.
If x5 did not make an automatic backup copy (if there are no other iwprj files, you could search your pc)
Then I have bad news, you need to start over.
You could try to search also for iwzip file (that is created in step5 for backup purposes, (export project)
But you need 1 of these files.
Create backups regurly especialy when you start, use step5 export project. And also the save button, or set the save options, these are found in the save button (pulldown)
But best is to make a regular backup in step5 export project and save it on another medium then you work on (usb mem stick)
