Unable to load blockchain

[samlspencer]

Hi, last night I initiated a transfer and the coins showed up but did not become usable. After 6+ hours of waiting I hit the button to reset the blockchain transactions and the worst happened. It now says that my wallet has 0 coins and that the file is corrupted as seen below.

"com.google.bitcoin.store.BlockStoreException Corrupted block store: could not find chain head"

Trying to reset does not work and has been stuck in "synchronizing" for a little over 2 hrs.

Any help will be much appreciated.

You don't mention which version of MulitBit you are using - I am assuming you are on a relatively recent version (ie one with encrypted wallets).

You should be able to fix this as follows:

1. Find where MultiBit is storing your user data - see https://multibit.org/en/help/v0.5/help_troubleshooting.html
2. Shut down MultiBit
3. Go to your MultiBit user data directory - worked out in step 1 - and delete the file multibit.spvchain.
4. Start up MultiBit again

It will then regenerate it and should start syncing.
After it has synced you should see all your bitcoin in your wallet.

I have changed the code so that it automatically deletes and recreates the blockstore as required. Will appear in 0.5.12

They might be hidden folders. Have a look here: https://multibit.org/en/help/v0.5/help_support_missingWallets.html
