I can't open adobe digital deiditions at all!

I tried to reinstall ADE again but, it doesn't work!

I used ADE & E-book properly, but at some point (I don't know when)

ADE doesn't operate.

In fact, it is open in the Winows task bar below the screen.

and it's blinking (saying activated).

But, the main screen of ADM is not opening at all.

I can't click the icon. it's not working.

Even if, I can see this small screen when I click ADE task bar Icon, but Main Program screen is not opening.

I can't find the solution.

Please help me.
