Earlier i was using version lower than 3.11.2, even after installing all critical updates on saturday itself, ZT didnt work today. So decided to uninstall current version and install new from your site. Now everytime i download, Only 3.11.2 is getting downloaded and thats not working on my system, giving multiple errors on opening.. pathetic service. You are only giving excuses. give proper link of version lower than 3.11.2
