Hello Adrian,
Besides the issue of which version you have (I don't believe that feature existed at 4.3), look also into which modules you have.
The Thermal Contact capability is part of the Heat Transfer Module (See www.comsol.com/products/specifications/heat-transfer/)
In v4.3, to check if your license includes that module, you will need to go to Options>Licenses.
Best,
Jeff
