invalid or unsupported file format and multiselect operation failed for .bin

[GreatScottish8932]

I'm trying to burn a game into a CD for my PSX, but there is a problem, that when I try use the "write image file to disc" mode and try to add the 23 .bin files AND the .cue file, it says that the tracks 2 to 23 are "Invalid or unsupported file format!", and then a message appears saying "MultiSelect Operation Failed! File: (the file location)", and then it asks me if I want to "continue with processing the remaining files?", i've tried only adding the .cue and the first .bin file (track 1), but then it says that I need to add all the other .bin files! I honestly don't know what to do, i don't want to try and burn the disc because its a CD-R and I don't know any way to unlock it after burning it and I don't want to waste any CDs! please help!
