Save File no longer recognized

[arceus342342]

Hi everyone, I just beat the E4 and saved @ the train station right afterwards, but had to close my file. On trying to open it back up, my game doesn't recognize my file anymore.

I've still got the file named game.rxdata, it's in the exact same save folder where it should be based on all the community instructions, with all my other save backups. When I open the Reborn player now to start the post-game, it just prompts me to start a new game, and when I try to check for other save files, I get a message saying I don't have any. I've tried deleting and redownloading the E19 player, and the same thing keeps happening.

I don't know what to do and as much as I want to play through the game a second time, I've had this file since E8 and don't want it to be lost :(  can anyone help?

Thanks so much
