After a few days of working fine, the error is back. I'll look into this and get back to you.

I've found a forum that shines some light on the subject. I'm running "-checkblocks=0 -checklevel=6" now, we'll see how that goes. https://bitcointalk.org/index.php?topic=103167.0

Seems to start working and then simply dies. I think it might have something to do with my encrypted file-system.

# Bitcoin-qt Not Syncing with errors

(Asked by: username_0 on 2013-04-19)

My bitcoin-qt (on ubuntu installed via the PPA) just plain won't sync. It's been running for days and no/little progress past ~82256 blocks remaining...
I've also got an error displaying "Warning: Displayed transactions may not be correct! You may need to upgrade, or other nodes may need to upgrade."
I've got a good unrestricted internet connection and plenty of RAM, CPU and HDD.
I even tried loading the client with instructions on here (bootstrapping)  http://eu2.bitcoincharts.com/blockchain/ to no end.
I've also purged all files from the .bitcoin directory (excluding wallet.dat of course) and started again to no end.
Can someone help?

Try starting with the `-reindex` command-line flag. That will rebuild the database on disk (as it seems corrupted), without redownloading the blocks you already have.

It's strange that wiping your datadir didn't help though.
