用EW PLAY的朋友，谨慎更新最新4.2.35，此版本不兼容之前自己做的模板
跟官方发了邮件反映了这个问题，得到的答复是：建议重做模板。
This is a known issue. 4.2.25 brought big changes to Play, and our instrument files had to be updated. With 4.2.35 you do need to rebuild your multi's you've made, and need to ensure you're on the latest version of the instruments files for all of your product libraries.
