unfortunately reconciling is one of the things quicken does very poorly with no easy way to fix it or unreconcile.
You basically have 3 options
1. load a backup file from before the reconcile and see if it will work
2. manually look through the register for the amount that you are off. You can sort by amount and see if there is 1 transaction for the exact amount and that would probably be your culprit.
3. give up and just put in an adjustment entry to get the balance back where it should be. ie if quicken thinks you have 300 too much make a withdrawal for 300. If quicken things you are 200 too low make a deposit for 200.
If you want to pay extra i am able to get you my phone number and log in remotely to work on it with you. But the above are the methods i would be using. i just might have a better idea on what we are looking for and how to adjust it.
