unrar problems

I seem to be having trouble creating the cdi file from the rars. I checked isonews and have the correct number of rar files that it says. When I open winrar and try to extract rar .001 it seems to start off alright extracting from each of the files, but then it seems to finish (100%) at file .016, when there are actually 26 files (msr). Then a error message appears saying, "CRC failed in extracting cdi". Can anybody help me?

Where you have files .001 .002 .003 and so on try re-naming them.
start with .rar instead of .001
then .r00 for .002 and .r01 for .003 and so on,when all the files have been renamed then extract.
you should then end up with your un-rarred file

Good Luck......
