start up browser wont open

Please recommend what can be done. As I enjoy using this program. I had a shortcut to taskbar. All of a sudden, when now when I click it to open to use it. the new browser page pops up for 1 second, then vanishes. I cannot click to open it or use it. It happens similar to how a pop up blocker works but I don't have a pop up blocker. Whenever I click open, it precedes to start opening, then it closes up. I've uninstalled & re installed many times. Now I can't even get a short cut of it on my task bar or desk top. Please help as I really like using it but now it will not open. I've tried everthing! From recovery points. This is the free version that wont work. I'm now leery to bother buying the Plus because this free won't evern open. I've had Vdownloader for over a year with no problems until now.

Thanks
