Hi. Did you buy and register GSX also? Because GSX Level 2 is an EXPANSION from level 1. You need to buy and register BOTH products to make it work.
Did you also follow the instructions on the Manual (Installing with the Antivirus off)?
When you see Level 2 in Trial mode, it seems like you installed it correctly, but you sure need both products registered to get it to work.
After Installing you also should close your simulator and start it up again, sometimes it gets active only after rebooting the first time.
