Do you get the same problems on a different data set, such as sample data? Or a different spec file? Sometimes these errors occur due to corruption in a data file or a spec file.

If you can replicate the problem in a different data set or file, could you indicate what process you are doing at the time of the error? This can help point to whether a file needs to be deleted and recreated, or other things.

Also, what is the file version of LedgerFinRep.EXE and also the \softrak\system\ads32.dll system file?
