DavidNicholas 3 Posted March 9, 2018 Hi, I recently downloaded the Twotter's V1.21, having bought one of the first XT versions, but on installation I find error messages that my username/serial number don't match. I've checked and rechecked these, and tried installation with and without internet connection. Screenshots attached. Help, please? Share this post Link to post Share on other sites
