The Report Tables are used by Adagio programs for doing Crystal Reporting and they are normally on the same drive letter as Adagio is installed. It appears when an install or upgrade was being done, the Report Table drive letter was changed to L, just re-install the programs again using the correct drive letter. This has nothing to do with the data.

How long would it take to re-create the AP data and can you? If you have started a conversion and it failed, I would be very careful of the backup copy. You may want to get a prifessional in to go over the system and to be sure you do not lose your current data.

Once you get the AP back, check that it balances to the Ledger. It is possible that they will not agree to each other.
