I worked in the Ledger most of this afternoon and all 2009 data was there. After I exited the program another staff member went into the GL and the only thing there was the balances and no data. I did an integrity check and it gave the following error "Posted transaction file corrupt". This is the 2nd time this happens in the Ledger. I've restored both times from a previous backup but would like to know what is causing this to happen.

Also, I upgraded to the latest versions of OE and Receivables 9.0 at dinnertime. There were posted orders in OE from the morning. None of these orders now have any details or history but they came over to the customers account in receivables. None of the items came out of inventory. Any thoughts as to what happened.
