Whenever I try to run the Qt wallet I get the error "error loading block database", is there anyway to fix this? I download the latest version and that hasn't helped.
Backup your wallet.dat and delete everything in C:\Users\yourusername\AppData\Roaming\ESP\, download bootstrap (

I followed you instructions and the wallet is working now thanks, just waiting for it to sync, I just have 3 quick questions:
1. What is the espers full client for?
2. I deleted the original wallet.dat file but there was no coins inside (they're on an exchange) is that okay?
3. I downloaded and extracted the bootstrap to the correct location but the wallet is still taking very long to sync, is that because this is the first time syncing the wallet?
Thanks again for your help
