Log on to your Medilink server.


Start Medilink Launcher but do not Login yet.


Wait for it to say MDS Subscription Active in the bottom corner.


Then click Login -> Medilink


Once in Medilink proper, double check File -> Registered Mode is ticked (and/or simply re-tick it).


Once the Server is fixed Workstations should automatically pick up the Registration from the Server, although you can also do the same as above.
