We've had various people have issues occasionally with compiling projects in DS-5 with the following error:
Error: C9932E: Cannot obtain license for Compiler (feature compiler5) with license version >= 5.0201301
System clock has been set back
Usually building again would clear the error. The reason this occurs is because DS-5 detected some files on your computer that are dated ahead of the current time. They have a utility available to scan for those files if you contact their support, and then there are a multitude of different ways to update timestamps on the files it finds.
In our experience, IAR has several files like these in the <IAR install dir>\common\ folder, so check there first and that may solve the problem.
