I realize I am not the person you asked but if you go through this thread it has been detailed multiple times how to delete the blockchain and start from scratch.
found here

And here (third post down #4 in the list)

And if you still cannot find it perhaps this instruction will help.


INSTRUCTIONS (Windows):

Go to C:\Users\%USER%\AppData\Roaming\Pennies (press the windows key + r and put in %appdata%\Pennies)
Delete everything BUT KEEP THE WALLET.DAT
Run the Pennies latest version 0.10.2 qt
Wait for the blockchain to download
done
