[Freesurfer] 'Invalid' license file

Hi, Our IT department have recently upgraded our cluster OS and now Freesurfer complains that its license is invalid. I have tried rebuilding, and acquiring a new license, but these do not fix the problem. The license file I am using works in my Ubuntu 12.04 computer - it has been copied across as a file, not via a text editor - and used to work on an older version of the same OS.

Do you know of any solution to this issue?

I've tried everything I have seen on the mailing list, including naming it .license and license.txt, checking for whitespace, etc. Our OS is now SUSE Linux Enterprise Server 12 SP1 (x86_64).

Many thanks, Lee
