I am getting the error message "object reference not set to an instance of an object" whenever I try to open ANY files from MS Word (2010), including those I previously translated in Studio 2015, as "translate single file" in Studio 2017. I read all related messages on this forum, and none of the solutions seem to help. It is NOT an antivirus problem, sorry. I also ran a repair on Studio 2017 with no results. Word is still the most used program for my source and target files, so this is very upsetting. Please help, thank you.
