Hi,
Try these to see if maybe accidently some sttings window is hidden behind Splash screen:
ALT+TAB (Check if mediamonkey looks same)
Press Enter or ESC after it gets frozen on screen
If you have AERO/Task Bar preview try to see if Preview is ok.

Try to install new one as Portable into completely different folder eg. like c:\MMstartTest

Which version of MediaMonkey do you have installed right now and do you have any Addons or Portable Devices connected to your PC?

First time I log in.
Until a couple of weeks ago, my MM worked perfectly, but know when I try vto open it it freezes once the MM logo window opens.
I have to cancel the programe all the time.
Lat week I reinstalled MM and it worked a couple of times, bit today this otion didn't work. Any clue to what might be hapenning?
