So I've run into some problems with both version of SAI before but, this is something I've never seen before. All of a sudden whenever I try to open any given .sai2 file - only .sai2 files though, .sai and regular image files seem to work fine - the program will start loading it, freeze for a little while, and then refuse to open it in favor of presenting a couple of error messages. One reads "Data Error (cyclic redundancy check)" and the other reads "Windows function call failed" (I can't get a screenshot of this one since it only appears for a short while).
I can't for the life of me determine what could be the cause of this. I haven't done anything to mess around with the program files, and I don't think there's been any updates to my computer recently that would somehow mess with SAI or anything like that. Can anyone give me some insight on this?
