looking for some help with the wallet crashing everytime i try and load it.

error looks like..

assertion failed!

Expression: pindex- >pprev ¦¦ pindex-> GetBlockHash() ==
(!fTestNet ? hashGenesisBlock : hashGenesisBlockTestNet)

if i hit ignore it shows could not find blkindex.dat.

anyone have a bootstrap of the chain, assuming that is the file missing?
