I have tried to sort this issue out but it does not work for a solution. I have been having an issue - general massive catastrophic system error failure - with my SDL 2015, when adding my client’s multiterm, and sometimes TM is added or system does not accept it either. I uninstalled and reinstalled SDL versions 2011/2014/2015 from my laptop trying to sort it out, but I did not succeed. Client updated their multiterm and TM, but again the problem persists and I can't seem to find a solution. Can anyone help? Thanks in advance.
