When I launch Abaqus CAE I get following error:

david@xxx:/opt/abaqus/Commands\$ ./abaqus cae
Abaqus License Manager checked out the following license(s):
"cae_xx" release 6.14 from Flexnet server xxx.yyy.zz
.

terminate called after throwing an instance of 'nex_PrimException'
Abaqus Error: Abaqus/CAE Kernel exited with an error.

I use ubuntu 16.04.2 64bit with an nvidia Quadro K420 (the problem is likely to be correlated with graphic card).
