Red error in play column

[mgrowolski]

Hi

I have just started to get this problem from yesterday and the program was working fine on friday. When I went to play a song nothing started and I received a red error message in the play display column. I have uninstalled the program 3 times and reinstalled, rebuilt the database and again it still does the same thing can anyone help me as I have a rather important gig tomorrow and need to take both my laptops with me just in case
