Been running geth fine since frontier launch. Today I start getting this.

tried updated geth
tried upgradedb
tried removedb multiple times (seems like it makes no effect)

Still can't get the chain to sync.

Can I just delete the Dapp and Chaindata folders outright?

Any help appreciated.

*corrected post title fixed typo*

--- Issue resolved ---

Order should be from CLI
geth removedb
geth upgradedb

import process begins. once that completes should see:
Import Finished

At that point geth was restarted with no issues.
