I'll give that a shot, thanks.
Also, I tried another program called ROMVAULT and it worked great, except it didn't recognize the .140 dat for some reason. So it only updated from whatever dats came with the ROMVAULT program. Is ROMVAULT just as good CLRMAMEPRO?
Last but not least, when updating, I have my zipped roms in a folder called roms and my CHDs in subfolders inside of the rom folder. Do I scan the whole thing? Are CHDs updated by CLRMAMEPRO too or just the smaller zipped roms?
First major update for me so thanks in advance for your patience.
