Thanks for the tip! Do you also happen to know where the old DAT files are kept? I can't find them anywhere on my PC but I can't add a new piece set until I can locate the backups of the old sets. Thanks.

My CM10 dat files are located here:
C:\Program Files (x86)\Ubisoft\Chessmaster 10th Edition\Data\Dat
Many thanks. I know where the main DAT files/ piece sets are kept, I just can't find the backups. Until I can delete some of the backups, I can't import my new set

Sorry, I didn't realize you were in the process of modifying a dat file. I *think* I understand the source of the problem. I guess you got an error message stating, "There are already 1000 B0_Expert II.dat backups. Please remove at least one and retry."
As far as I can tell, the error message is not due to too many backups (I don't think there are any), but it's because you're trying to modify a file that's in a protected program folder. Try running the DatTexExtract program as administrator, and I don't think you'll get the error message.
Hi,
Could anyone with experience of modding this game (boards and pieces) contact me by private message?
Thanks!
