This message is displayed when AQTime fails to locate plug-in information in the plug-in file. Typically this happens for one of the following reasons:
The plug-in file is corrupted.
The plug-in is not supported by the AQTime edition which you have. For instance, you try to install a plug-in from the Pro edition into the Standard edition.
The major version of the plug-in does not match the major version of AQTime. Only those plug-ins that have the same major version number as AQTime are permitted to be installed.
