Upload that file Screenshots\\readme.txt so we can check what algorithm and settings are used to calculate that crc

Bingo, it's just the classical FCS32 checksum.
This script for quickbms can show you this value for all the files you select:
Code:
get SIZE asize
encryption crc 0xedb88320 "32 -1 -1 0 0 1"
log MEMORY_FILE 0 SIZE
get NAME filename
print "%QUICKBMS_CRC% %NAME%"
Example:
1258410340 readme.txt

If you can edit the crc field in that configuration file it would be a lot easier.

Anyway crc collisions are possible so you may have some chance but it's not so easy and requires some skills (I can't help you so don't ask).
