IF you are running e.g. WebAlign for automated conversion or lores generation you could expect an error message #7.
This message will appear in case of a problem during the audio conversion, e.g. if there are invalid frames in the source file.
By default WebAlign will try to handle this file again and again which will cause many error messages.
If you want to reduce this there is a setting inside the main window for the table settings: Maximum error counter for format conversion. By default this value is set to 0 but you can set it to e.g. 1
After reaching the maximum number another error message will be printed to the log file (and log window) to inform you that no further actions will be done on this file.
