Worked...thanks!

good to know... I did find the .dat file but still uncertain how to overcome the runtime errors loading the db.

MinGW Runtime Assertion
Assertion Failed!
Program:C:\Program Files\Quark\quark-qt.exc
File:db/version_set.cc,Line 789
Expressions: dummy_versions_.next_==&dummy_versions_

If I re-dl and install the wallet, can I reference the previous .dat file?

I purchased QRK on Cryptopia and downloaded the 10.6.3 wallet. After generating a wallet address and sending to funds to said wallet address, I realized that I didn't encrypt the wallet, though was able to generate a wallet address without doing so. When I attempt to load wallet application, I’m receiving an error that block db isn’t loading. When I attempt to rebuild the db, I receive a runtime error.   Will downloading and re-installing the wallet enable me to access the original wallet address w/o a private key?  Any insight is appreciated.
