1. download any .mtx file from downloads section on mektek - smaller the better. 2. open it within MTX Client - let it do all stuff it needs. 3. wait until it spawn an error - press continue. 4. shutdown MTX Client via its menu or manually via Task Manager. 5. start MTX Client again - should be Online now.
i know it's a stupid method but i suggest you to send all your Hate-Rays to developers of that stuff because even a china 8-years-old virus-maker can made this thing better than they did
