cant get past splash screen

If I click on the UM icon , the splash screen appears , it get to the " initializing audio engine" and that’s where it stops , occasionally it will get a bit further , but then I get “Something bad has happened to your program”.
I have tried to un install and re install but to no avail.
As a working DJ I am slowly losing confidence with this software.
