Problem combining licens files Matlab 2013b 2014b 2015a

I've installed the FlexLM on a Win 2008R2 server from the Matlab 2015a media. The licens for 2013b is working but when i add the lines for 2014b and 2015a i get this error.

From the logfile:

I can send the license files used but I don't want to post them here.

Before digging into in deeper: You do not need to combine the license files. Just uses the most recent one and you can work also with older releases.

[Tomas Enkvist]

The original file was for 2013b and the new one is for 2014 & 2015. So if I use the new one only will the clients that are running 2013b software on their PCs still work?

[Andreas Goser]

Correct. Just use the R2015a file on the server. The clients hopefully have the simple syntax with the "SERVER" line and "USE_SERVER"?

[Walter Roberson]

A license file for a release permits the use of all previous releases of the same software, back at least a decade. (There was a point at which the license mechanisms became incompatible; it might have been R12 in 2000.) This does "use up a slot" of the newest license, so if you had some stray licenses that were not brought forward in maintenance then you might want to handle their licenses differently.
