If you encounter a bad PLA file error message, [contact us](https://dc-help.vas.com/GetStarted/ContactUs.htm) for support.

This error message is related to PULSE. A bad PLA file prevents PULSE from properly updating with your DC305 data. This message often displays as a separate message box after restarting DairyComp. In some cases, you might have seen and closed this message previously.

If you receive a bad PLA file error message, or if your PULSE isn't refreshing with DairyComp, [contact us](https://platform-docs.vas.com/en-us/Content/Platform/GetStarted/ContactUs.htm) for support.
