I downloaded the new wallet, ran it and it came up with 'wallet.dat corrupted, salvage failed'.
wiped the blakestar folder (in roaming), and tried again, it worked fine with a new wallet.dat, so i put my backed up wallet.dat back in and the same error.
Ran the old v1.0.0.1 wallet exe file (didn't reload or anything) and it worked fine, so let it sync under the old wallet, as it hasn't been running for around 8 weeks, and tried the new wallet and get same error.

is there anything obvious i'm doing wrong?
