Hi Sonia,

The original problem is that the Ledger.exe and the program dictionaries were out of synch - one of the these files did not actually get installed. The report tables you referenced in fact are not part of the problem. If you don't have the new data file GLNUMB'3 in your data directory, this is why the program keeps asking to convert the data.

As Doug mentioned, the service pack should be re-downloaded. And yes, you should put back those two report tables first. As long as their file dates are not newer that what will be installed, any files that require updating will properly be replaced.
