WMC purse history
The history of the WMC purse is stored locally on your computer in the database file.
If you do not see the history for this purse and there are some unpaid credits then search for the database file (*.sdf extension) which you used before and try to indicate it to the Keeper. Or if you used another computer when you accepted the credit, then log in from that computer.
If you have not found the database file then you should add funds to your WMZ purse to the amount sufficient for repaying the credit and wait for it to expire. Without the database file you will not be able to repay the credit prior to the scheduled repayment date. In the event of automatic repayment of the credit your BL and credit history will not suffer.
