Reading licensefile

My company recieved a large NF license after acquiring a broke company. I contacted the supplier of the navision license, and they mailed me a license file called navi_inf.dat & license.txt They told to copy the files to the directory from where the program was run and then restart it. My problem is as follows: I cant get this procedure to work, i suspect i miss something? any suggestions?

NAVI_INF.DAT is the license file for the old character based Avista/Navision, not for Navision Financials. If you are using the old Navision software you have to place this file in the directory containing the SERVER program, then stop and restart the server. If you are using Navision Financials you have to get a Financials license; it’s usually called FIN.FLF.
