Have anyone encountered this problem before? I was using Enthuware's ETS viewer for giving mock exams. All of a sudden since today morning it's giving me a error "Cannot start the application please reinstall" when I try to access the ETS viewer. I reinstalled and checked but still didn't work. Please can anyone provide me a solution? I emailed the enthuware support team also. I am having my exam soon so I need to finish the mock exams at the earliest. Please help thanks in advance.
