Hi - Sunday night on an airplane. Iíve been at NEAF/NEAIC. Doing the Comm Center I noted this post but did not know any context. You have 8.1. A W10 update locked it. You need to run the 8.1 installer to repair. Then ACP will start allowing you to enter your license. Then finish with 8.2. Now that I have seen the emails I get it. I can go online and fix it in 5 minutes. 8.2 is immune to W10 updates. Let me know when we can get together. Very bumpy and hard to type on iPad haha
