SmartFTP cannot start after update to 8.0.2276.0 from 8.0.2275.0

Hi, today I update the Smart FTP Client to version  8.0.2276.0 and its cannot be start up anymore.
Tried many methods, doesn't help, reinstall, uninstall, registry clean, all done.
When I try to open it, nothing happens, looking at the Task Manager, its start then closes in "Details mode."
The system is Window 10 64. licensed Enterprise version untl 2017-05-05.
Below is the error from Event Viewer:

Hi, nevermind, found out already, there is a file missing which cause the DLL cannot be start up, once the file restore (from Dropbox) then it can be startup again.
