No, in my experience the license shouldn't really prevent you from at least being able to see all of the devices and upload/download.
For the PLC, you have to go online and change it's IP address.
Then in the project, you have to open the PLC's properties and set the IP address in there, or remove the option to use the IP address configured in the project. If not, it defaults to like 192.168......, and will reset the PLC's IP address when you download.
For the HMI panel, configure the IP address on the panel itself. Open the HMI panel's properties (right-click on the HMI in the project tree and select properties), got to the Ethernet addresses, and just like the PLC, either configure the IP address you want, or remove the option to Set IP address in the project. IF that option is selected it will change the IP address to whatever is configured in the Ethernet addresses (both the HMI and PLC)
Just noticed you were in Louisville, so am I. Didn't know anybody did much with Siemens here.
The PC's IP address must be in the same subnet as the IP addresses of the HMI panel and the PLC.
Assuming you're connecting everything through a switch?
