You need to get an upgrade for the software

You can upload the program online. Of course you wont get the symbols and comments etc.

Or, you can ask the original programmer to export the program as STL source, which you can import into your older STEP7.
And likewise the original programmer can export the symbols as .DIF, which you then can import.

edit: But if you have a new CPU that is not supported by your STEP7 5.1, then there is no way other than to get an update.
