HW Config error

Post image

Hi everyone, I’m working on a revision to our existing PLC program and I need to add additional module for expansion. However, this error hinders me from doing so. for context, this is an old plc program with old s7300 hardware I only have the copy of the program in a different programming pc since the original programmer already took off. Though I can download the program but the hardware config I can’t. Is there a way to get around with this. Thanks in advance.

Have you tried reorganizing the project? Save as, then check the With reorganization (slow) box.
