Your Block diagram was so clumsy and u need to concentrate more on LabVIEW Basics for good programming practices.
1) There is no delay inside ur while loop it shoots ur CPU usage to maximum.
2) U wired a false constant to the while loop which makes ur loop to run indefinitely.
3) I dont know in which loop ur programme got stucked.
Find a small example.
