I have installed the license file on a new server, but I am having trouble getting a license
On Linux, the path to all license files used are stored in a file called .flexlmrc which may overwrite the LM_LICENSE_FILE environment variable. Look in your home directory for the file .flexlmrc. Delete this file.
On Windows this is located in the registry. Open regedit, locate HKEY_LOCAL_MACHINE->SOFTWARE->FLEXlm License Manager. Delete the NORSARLMD_LICENSE_FILE entry.
