Licence problem

I have the following error when I try to use icc:

Error: unknown string
License file(s) used were (in this order):
    1.  Trusted Storage
**  2.  /opt/intel/licenses/NCOM____XXXX-XXXXXXXX_1.lic

icc: error #10052: could not checkout FLEXlm license

The licence file is at this location

/opt/intel/licenses/

My machine does not have an Ethernet port and I used the MAC of my wifi card for the licence. I am not sure if this is related to my issue.
