Do you get a "no valid license key found" message on the software startup?
If yes then it is a license key issue.
If no then it has nothing to do with the license key, but the software does not see your controller and cannot communicate with it.
This is likely because the network is not setup correctly.
Did you setup the network (IP/subnet mask) as described in details in the UC300ETH-5LPT manual?
If so then what does the UCx00 utility tool says when you testing the connection?
