Always But i am getting an Error message that caliber Interactive is Not Licensed sufficiently, anyone here faced this error before? Any solutions?

check the hostid in your license.dat file
it should be the same hostid of your machine

Hi Islam, thanks for reply, the HostID is the same MAC address of my pc

probably it is caused by the old version of "mgcld" file.
Trying to use the latest mgcld which is installed along with your calibre to start the lmgrd.
You may find mgcld in your tool installed directory and modify daemon path in your license
file.
