Problem with .cab file

[madmax4]

During the installation of the enclave i get the following error message:

CRC error:The file c:\program files\starbreeze studios\enclave\sbz1_spa\waves_2.xwc doesn't match the file in setup's .cab file. the medium from which you are running the setup may be corrupted;contact your software vendor.

ABORT-RETRY-IGNORE

the size of wave_2.xwc file is about 26,6 MB. is there any program that i can extract this file from its archive (data4.cab, 3rd cd) and recreating it again,so this message won't appear again? the game starts normally after i press the ignore button, but this is an annoying message which i would like to dissappear.
I try using i6comp but didn't help(or maybe i didn't try any harder)
is there a possibility to fix it?Thanks in advise...

As this is not a question about backing up a game disc, you will need to contact 'Tech Support'
