Duke. I know this is extremely difficult. Put aside any thoughts of what wife may or may not have done. You have no control over that. Get visitation with your daughters set up ASAP. You can only help your daughters with ACTION right now.
So your ex is taking the low road. Shame on her. The day will come when your daughters will see, WITH NO VERBAL HELP FROM YOU, exactly what their mother did to alienate them from thei father, and they will resent her for it. This is not an if...it is a when.
Once visitation is set up, get them into counseling if you think it will help. Make a promise to yourself to say nothing to them about their mom. She's damaging them, you don't need to add to it.
Be the best dad you can be. Girls need their dads to be strong and kind. You CAN do this. Be the better parent, put their needs at the top of your priority list.
