The first thing I would recommend is its re-installation. Backup the data you have, then re-install the application. Next time you want to start it, make sure you are logged in with an Administrator account. Right click it and always start the program as Administrator. The software should work this way, because re-installation copies original files and repair any broken registry entries.
Secondly, if you're keep having issues with the software, access the official website an get in touch with the support team. They will provide further assistance to the problem.
