How to manually restore a screen from a .bak-file

[bos]

I'm new in this iX-Developer.

I created a button which will open a new image and choose the image in the drop down box.
Since then I correct the name of the screen, and of course the link does not work anymore.
But when I validate the project disappears all the graphics on the picture I changed the name of.
There are only a graphical text that says:

"This screen could not be opened. The original screen was saved with the .bak extension in the project directory. The original file can be used to manually restore this screen."

How can I restore this manually??

Then I'll make a brand new screen and save the project, but when I open the project again the same happend for the new image.

What matters prior to the graphics on the screens disappear?
And how do I restore my work from the .Bak file?

Can anyone help me?

Can you send me a copy of the project? (Go to the directory where it's saved, zip up all the files and delete the tmp directory).

I have not been asked about the .bak file and will have to research this.

According to the developers, they will need a copy of your project as I indicated earlier to debug the problem.

Hope you can tell me how to re-generate the screen.
Thanks.
