HI leolv ,.
The error message means your CW doesn't find correct license on server.
First ping server from client, make sure network ok.
then change license file
FROM: this_host
TO: Your license server's host IP address, or your license server's host name
make sure the license.dat file is installed under both server FlexIM folder and client CW install folder.
Restart computer after everything set up.
If still has problem, create a private case to NXP license support team, with you license file. As it is related with personal asset, we can't post ti to public comunity.
Have a nice day,
Jennie
