Nuttplayer question

I downloaded nuttyplayer coz the built-in player does not support .srt but unfortunately it was stuck on the logo part(were the film(?) is going upwards infinitely). I waited for an hour because maybe it just building a list or something but it is still stuck.

Here are the things that I did:
-restart
-reinstall
-turned off the phone and removed the battery

Still does not work :/ what should I do then?

Z10/bb10.2.0
