cTrader doesn't start - the second day

Hello

Since yesterday, after starting the program the window doesn't pop up. There was information about loading the workspace confirmed and the conformation sound as well, but the program is only visible on the quick access bar as seen iin the attatchment, but you can not open and maximilize the window. I already tried to deinstall and install it - without effect.

I have Windows 10.

thanks for support
