" -1 - An error has occurred.
It was not possible to copy the selected file."
This message resolved itself when I uninstalled the core product before installing the Pro version.
However, now the backup fails in what appears to be an infinite loop while attempting to complete the Initialization process.The green bar proceeds to about 5%, then resets and starts again, repeatedly. It also appears that at each recursion a new backup file is created. The first seems properly named, but the others have " (no description)" in the description field. The longer I let it sit while trying to initialize, the more of these files are created in the manage backups screen.
This situation does not appear to self terminate. It forces me to navigate away from the screen in order to get out of it (i waited about an hour once, creating a few hundred of the "no description" files). When I navigate away, a red highlighted error screen flashes briefly, but does not remain long enough for me to read everything on it. In part it says:
Ajax loading error:error.
Inspection of the log file did not, to me, provide any clues of errors, the last entries in the log file were:
[100826 20:04:41] ----- Finished operation 2 ------

The log file stops abruptly at this point.
