You're right, I was more angry at Kingfiles after spending the whole day uploading to find it all in vain. In fact I tried again and guess what more corrupt files. It seems Kinfiles doesn't like you uploading large stuff.
I've noticed everyone is downloading the par2 files unnecessarily, you don't need to. They have been provided just in case.
If you do need to download quickpar for windows and download the first par2 file(*.par2) and run it in quickpar. Quickpar will then verify the parts and tell you if everything is ok. If not it tells you how many blocks you need so you need to download the other par2 files(*.volxxx+xxx.par2), these are the files with recovery data. the first number is how many blocks are in the proceeding files, the second number is how many blocks are in that file.
