I can without problems download a program from the LOGO! to the PC and also upload a program from the PC to the LOGO!. My suggestion: Create a Support Request.

This type of problems come up when you choose the wrong LOGO! version in the software. Other than that, it is an issue for Siemens' support team as @ixo65 suggested.
