So I purchased a 3-year license plan today and I downloaded Cubism Editor today. After entering the license key, nothing had happened. So I tried again and input the license key again and got the notification that "license is registered. please deactivate and try again (6)". I have not gone past this point and am stuck in the first part where I only see the pro and trial license activation, purchase pro license, start pro version free trials, and start as free version. I can't deactivate and I can't get into the live2d program. What am I supposed to do?
Software Version: 4.1.00
OS: Windows 10
PC Model: Dell 2405FPW
GPU: NVIDIA GeForce GTX 960
CPU: Intel(R) Core(TM) i7-4770
Memory: 16 GB
For purposes, I crossed out the license key.
