Hi, it seems this activation problem happened to a lot of GW user. If you search “activation” topic in the forum, you will find some similar topics.
This has happened to me for quite a lot of times, every time my GW Basic got de-activate, I have to contact GW to help re-activate my GW Basic because I have been inserting my activation code too many times that when I re-activate it, “This key has already been used multiple times. Please contact us so we can help.” message pops up.
And to be honest, now I just let my GW in the free version since many months ago (yes I kept it, not uninstalled it because I think GW is a good software) rather than keep asking for help and got de-activated again until now.
So, is there any solution to this problem?
