Could someone help out please?
When I start bitcoin core, I get "error opening block database, Do you want to rebuild the block database now?" If I press "OK", I get "error opening block database"
What can I do to get my wallet working again?
Thanks.
Manually Delete then re-download the block chain.
It should be in .bitcoin folder in your user app data folder(%appdata%).
Your location may vary depending on the version of windoze you run.
