You may try to download the more recent version of the simulator which has been upgraded to QuestaSim, however you will need to request a free licence. The instructions to follow are detailed at VHDL Whiz, and involve extra steps such as filling out a form for a licence request with your network card's MAC address and installing a license file. I'm sure it will be fine ;-). For the impatient, stick to ModelSim ver 20.1.1, it will do well enough.
