First i found your team on youtube and i download svp free versiyon for bootcamp windows 10 on my macbook every things alright i fall in love what you done. Then i start watching all movies with svp. I watched more than 20 movies no issue.  3 months later player starts to hangs/freez no reason. It only play 1 minute then hangs very bad then stop working.

I do everything what i can. Reinstall windows 10 reinstall graphic card driver format and install windows 8.1..... etc.  but same result It only play 1 minute then hangs very bad. No error (red) message on events log
