All blocks and hardware disappear with Step7

Hello,

I have copied a good working Siemens Step 7 project to mine
notebook installed with Step 7 software.
Now when I opening the project I see only an empty OB1-block
(all other blocks are gone)and an empty hardware configuration.
How is this possible?
Problem with the hardware update on the notebook?
Who have the answer?

Greetings,

Did you use the Archive and Retrieve functions ?
My guess is that you had an empty project opened alongside the real project, and accidently selected the wrong project when you used the archive function.

You are right Jesper.
Using the retrieve function and it´s now good.
Thank you for the help.
