James, I don't know how long you have been keeping 
your books, or when these mistakes began to show up.   If you have 
your brokers statements, you should be able to start at the beginning of 2006 
and work forward, verifying all entries agree.   When you find a 
misentered item, you can edit it to make it right, or delete and reenter, just 
use the actual figures and dates acording to the broker.   Be sure you 
have only one valuation saved for each month, on the date specified in your 
PA.
Before you run an Allocation of Earnings for 2006, 
make sure you have an allocation report shown for the end of each prior year, 
especially 2005.    
 
If there is some out of ordinary transaction you 
may have misentered, write with the details, so you can get specific advice on 
that transaction.
