Try this...try opening TPM, starting the first level, and saving off several bogus games with different names. Those save files will be created with zanzi00 etc. etc. THEN try copying over those save files with the ones you already have. I bet that will solve it.
TPM, I believe, has a file stored somewhere that includes the save file names, and I bet you can't load a save game unless that file name list includes the save game filename in question. (I don't think I could be any less clear, do you? Let me know if this doesn't make sense.)
