Hello [name]! Thanks for joining the GMC. Before making any posts in the Tech Support forum, can we suggest you read the forum rules? These are simple guidelines that we ask you to follow so that you can get the best help possible for your issue.
If i upgrade from gms to gms 2 does it void my gms license and all the modules? For example can I still run gms on my laptop and run gms 2 on my desktop? Or once i upgrade to gms 2 i can no longer run gms?
You can use both GMS 1.x and GMS 2 at the same time. Previously bought licenses remain valid even after claiming your upgrade discount and getting a license for GMS 2.
They are separate products. When you buy you don't update, but just gets discount From September there will be no difference if you already have GMS1.4 or no, as prices will be same for all customers.
