you can modify one of your other cue files to work with the .bin that you have.
Change the name of the .cue to match the name of the bin (everything should be the same except the extension), then open it
with Notepad. Once there you'll see something like this:
Just change the file name that's in brackets to the EXACT name of your .bin file.
FILE "Symantec.Ghost.8.0.Corporate-SoSISO.ShareReactor.bin" BINARY
TRACK 01 MODE2/2352
INDEX 01 00:00:00
save and close. Now it points to the correct bin.
This works 9 times out of 10. As for the nfo's, they're generally just extra installation instructions or serial numbers.
ShareReactor has started making the nfo files on it's releases available for viewing without actually download them with an ed2k
client, so you might try there if it's a recent release.
If not, just tell us what it is, maybe somebody's got the nfo lying around. I know I save all mine, just in case...
