I bought an orchestral essentials from https://projectsam.com/ website. In the latest update or your updates, there was a problem and I cannot close the sound within Sibelius 7.5.1 and I cannot get the piece back. The sound does not close, but if I turn off the Sibelius software, it can be a way of salvation. I have no other way of salvation.
How can I get rid of it?
