My client will start again to download the blockchain without the blkindex.dat
Is there a way to download it?
Start using -rescan and it will create the blkindex.dat
That didn't seem to work for me. It seemed to download the chain from the network anyway, appending it to the blk000x.dat files. At least by speed and filesize it appeared that way. I've been told the most recent bitcoin source (not 0.6.3) has a feature to import blk000x.dat files and build the index.
