Detail Cust. Ledger Entry Problems

We have upgraded a client from 2.60 to 3.60. We are experiencing some quirky data (problems with Rec-Pay from GL, wrong data in past due amounts on cust overdue warnings, etc.)We checked the primary & secondary keys, but cannot find any problems. Any one run into this on an upgrade?

Did you follow the upgrade procedure ?

Yes, we followed all the procedures that we are aware of, and have had no other problems other than this one problem with the detail cust ledger entry, and the detail vendor ledger entry tables. I know we must have missed somthing, but right now, we are at a loss.
