SDL MultiTerm 2015 installed but won't open - completely up-to-date

Hi,


Today I downloaded and installed MultiTerm 2015 for the first time to use with Trados Studio 2015. Both applications are entirely up to date but MultiTerm will not open. When I click on the icon it says "SDL MultiTerm has stopped working". These are the details provided by Windows:
