I hear that many people get CRC error at extraction and duno what to do so i decided to meke this threat for them.
(I had crc error on extraction to but i fix it)

CRC Error Reasons:

HardDisk Scratch(20% Chances or lower)
Archive is realy corrupt (5% chances or lower)
RAM MEMORY CORUPTED (85% chances or higger)


NOTE: IF YOU BUY A NEW RAM MEMORY AND GET CRC ON EXTRACT TRY PUT THE OLD RAM AND DOWNLOAD SOMTHING AGAIN AND SEE IF YOU STILL HAVE IT.....IF IT'S FIXED GO GET A NEW RAM...
