That's good advice above, particularly if you've already done what i suggested in Post #170: "Perhaps you have a problem with GIR_Editor itself so to eliminate that possibility you should re-download it....". Clearly the fact you've had no success opening multiple BIN files points to either a software or OS propblen.

In brief, if you've ruled out GIR_Editor itself as the problem then indeed it is a PC issue. If your AV is not interfering with running the stand-alone program which you can easily test by temporarily disabling protection while also disabling internet connection, then consider if other resources on the PC needed by GIR_Editor are not available to it or already in use - even though that's very unlikely to happen on three different PCs.

Regardless, PC or related program issues aren't what we try to solve in this forum. Good luck.
