LW will attempt to redownld that portion where it detects any corruption up to 6 times before it gives up. Sometimes it's worth doing this because on the alternate efforts to redownld the last part, it can be acceptable/successful by LW which suggests some missing bits of data be they as small as 1 bit or byte. But then sometimes it goes thru all 6 times without success. But that still doesn't mean it can't be used. But that depends on what type of corruption it is. (Oh other reasons for corruption ... old & unreliable modem/router, poor connections with cable, unreliable transmission (high packet loss of data) due to ISP over transmission lines. There's prolly more reasons also.)

wondering why ... np keep it in mind for future.
