Error : CLR20r3

I have CLR20r3 error when I am trying to use sounds provided from Syrinscape but its not from Syrinscape software but from file called SyrinscapeURIProxy.exe. Every time when I try to make sound for skill inside of Fantasy Grounds the error appears. I have all the necessary files that have to be in FG extensions directory and everything is up to date starting from graphic card drivers/ Java / Framework etc.etc… all the most important software is working fine but this single URIProxy gives me crash. Any idea what can I do with that ?

Are you using the very latest version on the Player that we uploaded today?

Check your version number under the settings cog. It should be 1.3.7-20180815
