fitbat wroteThank you, still so.
Did you put jv16PT.exe in the Symantec Ignore/Exclusion list or HistoryCleaner.xdat or both?
If so, the last thing I can think of is the file HistoryCleaner.xdat being damaged during download or the expansion.
In that case, as a last resort, you could try:
1.re-download jv16PT2010-build 986 from http://www.macecraft.com,
2.Uninstall jv16PT2010 completely, keep nothing,
3.Install jv16PT2010-build 986 again using the new download!
Last thing to do: You can run jv16PT2010 in DEBUG mode (press Ctrl+Shift key, DEBUG appears in main window menu bar, click DEBUG, enable Debug mode, and restart jv16PT). On the desktop appears the Debug Log.html icon. Now only execute the HistoryCleaner tool. After the error "can not access HistoryCleaner.xdat" appears, close jv16PT2010, .zip the Debug Log.html and attacht the .zip file to this forum thread.
Hopefully the developer (jv16) can see why HistoryCleaner.xdat can not be accessed.
