Repeated error synchronizing Bitcoin client I've tried unsuccessfully 2 times to download the application from this site https://www.weusecoins.com/en/getting-started. Last failure stopped at around 16,000 blocks. I am trying to get setup with a wallet and begin buying BTC's. I do not want to use an online wallet service.

The only other applications that I had open during the download was Firefox and I use AVG Free Antivirus, but do not know how to disable it. I have restarted the OS.

What to do?

Thank you very much in advance.
If your computer is overclocked, this may fail repeatedly. Even overclocks that are stable in other situations can fail during this CPU/memory intensive sync process. Go back to stock settings and try again.
