This message can indicate that you are running a older version of the FLEXlm license server software that is not compatible with the license file that you have installed. This can often happen if you upgrade your development tools, for example from ADS 1.2 to RVDS 3.1.

Another cause for this error message is that you have changed non-user editable parts of your license file.  For example, you may have a three server license and have commented out two of the three server lines.  The only parts of the license that you are allowed to modify are the host name (not host ID) and the port number.  You can, however, add certain arguments to your license file provided that you follow the syntax provided in the FLEXlm/FLEXnet user documentation.  For instance you can define a port number for the armlmd vendor daemon, or a path to armlmd, in your license file.
