Combining text and sound in more than one routine causes freeze

Windows 7
PsychoPy v1.84.2
Standard Standalone

Trying to combine text and sound in more than one routine causes the program to freeze. I wish to play a .wav lasting 60 seconds, with a short instruction included. Then I wish to play it again in the next routine, while several text stimuli are being shown consecutively.

Playing the .wav two times works fine, playing it once with text also works fine, but I can’t play it two times when text is included. The experiment freezes, I open task manager to exit, and then I get a message saying “pythonw has stopped working”. I’ve tried reinstalling the package, but that didn’t change anything. I don’t know how to code, so I’m stuck.
