A nasty problem with SB games

[Rabbit]

I think I may have seen a similar error (a single hex displayed) when I have tried to open a scenario that was incompatible with the title or if I hadn't loaded all the necessary files for a particular scenario. However it sounds like your issue is different from that. One thing I found weird is your dialog box that says "Modem Error" at the top. That would seem to suggest you have the Direct-Play mode enabled; although I can't speak much to that since I've never used that feature.

I did a search on "error reading battle file" and the few hits I got seemed to relate to file corruption. My best WAG guess might be that your issue has something to do with Squad Battles being unable to access the files for some reason. It could be due to account permissions, file encryption, file corruption, etc. or perhaps you have some antivirus app that is blocking access. But overall it seems like Squad Battles is unable to access the files (or folders in which the files reside) correctly.

Sorry this isn't more helpful. I am just trying to provide some sort of feedback in case any of it might somehow ring a bell with what you are doing.
