This happened to me a week or so ago. Apparently TT was working on a fix and when I went back in the next day, I was able to install it and activate it. There is another thread somewhere in this community discussion about a customer service number you might be able to call to help get it activated. I was in the same situation as you - had used TT for years and wasn’t sure what I would do. It’s very frustrating and they should have had it fixed by now instead of driving people crazy.
