我用CCS6.1导入NFCLink的代码会报错：This project was created using a version of compiler that is not currently installed: 4.4.4 [MSP430]. Please go to <a href="liveaction:OpenAppCenter">CCS App Center</a> to install the compiler of this version, or migrate the project to one of the available compiler versions by adjusting project properties.
编译器都已经是最新的了，在advanced settings → Complier version 里也没法选择4.4.4版本，要怎么解决
