Why is it when i open up sapien and open the scenario tag or the scenario it sounds like its opening but... nope it closes can sum1 help me plz

I use to have that problem, it's something with the Sapien Tag's, like when you try to open sapien it will try to read this corrupted tag, and it won't and Sapien just shuts down. The only way I know how to fix it is by Uninstalling HEK and reinstalling. There may be another way but this is how I did it.
