Very likely the RAR file is corrupt and if its not from a source you trust then more so that its corrupt and maybe malware infested.
If its a source you trust ask then to ZIP the file rather than RAR and try again. Odd occasion you may need to disable your anti-virus application and then un RAR the file, but in most cases with CRC errors the file is corrupt.
