In the other project where are siemens drivers ( inverters, servos ), I have same trouble.

I'm not sure if this is your issue, but I've seen Simatic Manager choke on projects that were saved on another workstation that had an optional package installed that wasn't used in the project. If possible, get someone who can open the project to go to File -> Save As and check the box "With Reorganization". It will take longer than a normal "save as" but it is supposed to strip out references to unused software packages. Then see if you can open it.

I'd offer to do it for you, but I don't have the software any more.

He can’t even create a new project so I would say to reinstall Drive ES/Starter 

or at least I  asked if he could create a new one…..

 

I have all the software 

post it somewhere and I will try to open it
