Could you possibly explain why after using CHDMAN, I get the following:

C:\MAME\ROMS\BLITZ99>chdman -update blitz99.chd blitz99r.chd
chdman - MAME Compressed Hunks of Data (CHD) manager 0.78 (Dec 25 2003)
Input file: blitz99.chd
Output file: blitz99r.chd
Compression complete ... final ratio = 82%
Input MD5 verified
Input SHA1 verified

C:\MAME\ROMS\BLITZ99>

Yet, after running SHA1 checking with CMPRO it still reports the following:

NFL Blitz [folder: blitz]
integrity md5 check failed: blitz.chd [wrong: 874f5e25722e67221dc85237b21d496e] [right: 9cec59456c4d239ba05c7802082489e4]

Is there any way to fix this? Please don't tell me I need to get new copies of these CHD's..? :(

I have this issue with:
blitz, blitz2k, blitz99, bm2ndmix, bmdct, cryptklr, jdredd and mace.

Any advice or assistance will be greatly appreciated.

thank you in advance.
